However, to resolve minutecomponents, optical and electron microscopic techniques are needed
The study of the nervous system relies on optical and microscopic techniques
If we cut the cerebral hemispheres in the middle, a new set of structures come into view. Manyof these perform different functions vital to our being.
There are many important structures hidden in the middle of the brain

esearchers start with the data and develop a theory or aninterpretation that is “grounded in” those data.
Grounded theory

Participant observation
Qualitative research can helpresearchers to generate new and interesting research questions and hypotheses
Strength of qualitative research
begin with a less focused research question, collect large amounts of relatively “unfiltered” data from a relativelysmall number of individuals, and analyse their data using non-statistical techniques.
The beginning of qualitative research
Combination Designs
Combination designs are a combination of different aspects of both the non-equivalent groups design and the pretest-posttest design.
Figure 7.3
I think this figure would be a good one to add into our textbook. This chart makes it much easier to understand interrupted time series and how the data from this type of study would be presented.
This is the tendency for many medical and psychologicalproblems to improve over time without any form of treatment.
Spontaneous remission
Thisrefers to the statistical fact that an individual who scores extremely on a variable on one occasion will tend to score less extremely onthe next occasion
Regression to the mean
pretest-posttest design
This method focuses on the bookends of the study. It only measures the first and last data point and ignores the journey between them.
When participants are not randomly assigned to conditions,however, the resulting groups are likely to be dissimilar in some ways.
When conditions are not randomly assigned, the groups tend to be different from each other. However, there are ways a researcher can use non-equivalent group designs and create similar groups.
content analysisrequires specifying keywords, phrases, or ideas and then finding all occurrences of them in the data.
Requirement of content analysis
Researchers are expected to demonstrate the interrater reliability of their coding procedure by having multiple raters code the samebehaviours independently and then showing that the different observers are in close agreement
One person's coding needs to be confirmed by others
here are two closely related issues thatresearchers must deal with before collecting data
There are two issues researchers must look at: the methods for sampling and measurement.
t does not matter how or where thevariables are measured
In correlational research, variables can be measured in any environment through the use of any method.
the definingfeature of correlational research is that the two variables are measured—neither one is manipulated—and this is true regardless ofwhether the variables are quantitative or categorical.
An important characteristic of correlational research

qualitative.
Research can also be non-experimental if it is qualitative. This involves non-numerical analysis.
single-variableresearch
Single-variable research: research that focuses on a single variable rather than a statistical relationship between two variables.
preferring non-experimentalresearch can be the case
Use non-experimental research when the question can be about a single variable, a non-causal statistical relationship between variables, a causal relationship between variables where the independent variable can't be manipulated or participants can't be randomly assigned to conditions, what a particular experience is like, or a broad topic.
Non-experimental research
Non-experimental research does not have an independent variable and doesn't assign participants to a condition
feedback that will help you improve the procedure
It is important to get feedback from the participants in order to refine the research process and design.
A pilot test is a small-scale study conducted to make sure that anew procedure works as planned
Doing a pilot test allows the formal research to go much more smoothly. It allows the experimenter to refine their process or conditions if the design of the research does not work well. It could also give the experimenter more insight into what group of people they had wanted to target. They may realize they need to narrow or broaden their targeted group of people.
which showed that students who expected their rats to learn quickly feltmore positively about their animals and reported behaving toward them in a more friendly manner
Your expectations affect your behavior. If you believe something will go well, you will act more positively towards it. If you think something will go poorly, you will act more negatively towards it.
experimenter’s expectations about howparticipants “should” behave in the experiment.
Expectations and attitudes have immense impacts on the experiment. A participant is going to want to give the researcher the outcomes they want to see.
xtraneous variables during the procedure
Extraneous variables can show up during the selection process. If each recruited person has a different experience with the experimenters, it can confuse the data and make the selection process less accurate.
participant pool
Participant pools provide easy access for researchers to collect data. However, they may not provide the appropriate population for the study. These pools may not provide the diversity, life experiences, and personal situations needed to perform the study.
at the start of any research project you should be thinking about how you will obtain your participants.
Every research study revolves around the participants and whether or not the researcher is able to work with them.
Prioritising Validities
It is often not possible to have high validity in all areas. A researcher needs to decide which ones are the most important for that particular study and work with those more closely.
operationalisation
Operationalization: converting from the research question to the experiment design
external validity
External validity supports generalizing the results to people and situations beyond what is studied. The results are connected to ideas that are outside of the realm of the work but can be related to the outcomes from it.
because the only difference between Darley and Latané’s conditions was the number of students that participantsbelieved to be involved in the discussion, this difference in belief must have been responsible for differences in helping between theconditions.
Example of internal validity
internal validity
Internal validity shows that two variables are related and that any differences between groups are caused by the independent variable
If a within-subjects design would be difficult or impossible to carry out, then you should consider a between-subjects designinstead
When considering which method to use, you should start with the within-subjects design. If it is not possible to use this method, then you should look into using the between-subjects method.
One is that it controls the order of conditions so that it is nolonger a confounding variable
By making sure the order of conditions is randomized, it does not add confusion to the data. The researcher can know the order of the conditions is not affecting the data to be a poor representation of the results. Using a random order of conditions provides the most genuine results possible.
One type of carryover effect
Types of carryover effect: practice effect (participants perform a task better in later conditions because they had the chance to practice), fatigue effect (participants perform a task worse in later conditions because they become tired or bored), and context effect (being tested in one condition can also change how participants perceive stimuli or interpret their task in later conditions)
The primary advantage
Within-subjects experiments are extremely useful because they are the best way to control extraneous participant variables
they are probably driven primarily bypeople’s expectations that they will improve.
Why do people's expectations and attitudes have such a strong impact on their health and the success of their treatments?
wait-listcontrol condition
Wait-list control condition: participants are told that they will receive the treatment but must wait until the participants in the treatment condition have already received it
placebo control condition
Placebo control condition: participants receive a placebo that looks much like the treatment but lacks the active ingredient or element thought to be responsible for the treatment's effectiveness
no-treatment control condition,
No-treatment control condition: the participants receive no treatment. This approach creates the problem of placebo effects. Placebo: a simulated treatment that lacks any active ingredient or element to make it effective Placebo effect: a positive effect of such treatment
randomised clinical trial.
Randomized clinical trial: the process of using treatment and control groups to determine whether or not a treatment is effective
participants are randomly assigned to either
Treatment condition: the person receives the treatment Control condition: the person does not receive the treatment
treatment
Treatment: an intervention meant to change people's behavior for the better
randomassignment
Random assignment: using a random process to decide which participants are tested in which conditions
t is essential in a between-subjects experiment that the researcher assign participants toconditions so that the different groups are, on average, highly similar to each other.
Even though participants are tested within different conditions, it is important to keep the other aspects of all of the groups the same. If you have more than one thing that is different, it is impossible to compare the results from the different groups accurately.
between-subjects experiment
Between-subjects experiment: each participant is tested in only one condition
confounding variable
Confounding variable: an extraneous variable that differs on average across levels of the independent variable
Extraneous variables make it difficult to detect the effect of the independent variable in two ways
Two ways extraneous variables make it hard to detect the effect of the independent variable: add variability or noise to the data and become confounding variables
manipulation check
Manipulation check: a separate measure of the construct the researcher is trying to manipulate
manipulate
Manipulate: to change an independent variable's level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times
extraneous variables
Extraneous variables: variables other than the independent and dependent variable
conditions
Conditions: the different levels of the independent variable
Incorporating Theory Into Your Research
To incorporate a theory into the research, distinguish the phenomenon from any other theories, identify existing theories of it, and come up with a hypothesis from it.
If a hypothesis is confirmed in a systematic empirical study, then the theory has been strengthened.
The hypothesis will prove to be strengthened if it is confirmed in a systematic empirical study. The hypothesis is weakened if it is not confirmed in this way.
Among the very best hypotheses are those that distinguish between competing theories.
To create an effective hypothesis, explore other theories on the same topic
It could be more formal and therefore more precise, broader in scope, more parsimonious, or it could take a new perspectiveor theoretical approach
Make the new theory more specific than the last one was
To construct a good theory, a researcher mustknow in detail about the phenomena of interest and about any existing theories based on a thorough review of the literature.
In order to build a strong theory, one must become knowledgeable about the phenomena and any previous theories.
creating a moredetailed model of “theoretically motivated” or “theory-driven” research
This approach helps the previous research improve in that it makes them more theoretically motivated and theory-driven.
stage theories
Stage theories: specify a series fo stages that people pass through as they develop or adapt to their environment
Functional theories
Functional theories: explain psychological phenomena in terms of their function or purpose
The Variety of Theories in Psychology
Theories vary in their formality, scope, and their theoretical ideas.
formality
Formality: the extent to which the components of the theory and the relationships among them are specified clearly and in detail.
What Are Theories For
Theories are used for the organisation of phenomena, making predictions, generating new research, and to see a topic from multiple perspectives through multiple theories.
theoretical framework
Theoretical framework: the context applied to understanding a phenomena.
theory
Theory: a coherent explanation or interpretation of one or more phenomena. Includes descriptions of variables, structures, functions, processes, and organising principles
Replication
Replication gives a further insight into the behavior the research is studying. If the study is done again and the results come out the same way, it establishes a solid behavioral pattern.
phenomenon
Phenomenon: an established answer to a research question.
Your concern with ethics should not end when your study receives institutional approval
It is important to maintain your ethics throughout the whole process. Just because superiors are no longer keeping as much of a close eye on the study, does not mean that the ethics present within it should weaken.
Once the risks of the research have been identified and minimised, you need to weigh them against the benefits.
Make sure the risks are worth the possible outcomes. If the risks are greater than the good that could come from it, then the study should not be done.
It is best to identify and minimiseallforms of deception
It is very important to make sure your study is free from each form of deception. In order to do this, the researcher should maintain clear and honest communication with the participants.
Once you have identified the risks, you can often reduce or eliminate many of them
In order to eliminate risks, a researcher should modify the research design, use a pre-screening process, and actively work to maintain confidentiality.
The very first thingthat you must do as a new researcher is know and accept your ethical responsibilitie
As a researcher, you should know and understand your responsibilities. It is not an excuse for wrongdoings if you did not know about the standards. Even if you have to seek out the information on your own, it is important to have a clear understanding of your role in the research.
Scholarly integrity includes the obvious points that researchers must not fabricate data or plagiarise
it is important to have data that is real and unique to the one particular study you are doing.
Deception
Deception: misinforming participants about the purpose of a study, using confederates, using phony equipment like Milgram’s shock generator, and presenting participants with false feedback about their performance.
Informed consent means obtaining and documenting people’s agreement to participate in a study, having informed them of everythingthat might reasonably be expected to affect their decision
It is extremely important to make sure each participant agrees to participate and is aware of all that the study entails.
that ethical conflict in psychological research is unavoidable
There is always going to be ethical conflict within psychological research. It is how you handle it as a professional that is important.
must take into account how each of the three core principles applies to each of thethree groups of people
ant researcher must take into account the three core principles: respect for dignity of persons and peoples, acting responsibly and with integrity, and social justice and responsibility to society.
Several basic principles can help you find the most useful sources
In order to find effective sources, first look at the most recent materials. Then look for review articles to provide summaries of the topic. A final thing to look for is empirical research reports that would address your question or another similar question.
The primary method used to search the research literature involves using one or more electronic databases
Using electronic databases is a great way to find resources about a topic. Because of the large array of content from different years, databases are an extremely valuable research tool.
articles inprofessional journals, and scholarly books in psychology and related fields
Research literature is made up of materials from two main categories: professional journals and scholarly books. Professional journals: periodicals that publish original research articles. Scholarly books: books written by researchers and practitioners mainly for use by more of these same people.
ncluding time, money, equipment and materials, technical knowledge and skill, and access to researchparticipants.
In order to evaluate the feasibility, a researcher must evaluate these factors. The question will be used depending on the results of the rankings in these categories.
the answer is in doubt, the answer fills a gap in the research literature, and the answer has important practicalimplications.
In order to evaluate the interestingness, a researcher must evaluate these three factors. Whether or not the question will be found usable will depend somewhat on how it ranks within these categories.
the interestingness of the question and the feasibility of answering it.
A research must evaluate their questions to figure out which ones are usable. In order to do this, the questions should be analyzed on the basis of their interestingness and the feasibility of answering it.
Once you have a research idea, you need to use it to generate one or more empirically testable research questions, that is, questionsexpressed in terms of a single variable or relationship between variables.
After deciding on a research topic, the next step is to turn it into an empirically testable research question. To do this, the question must have a single variable or a relationship between variables.
Three of the most common sources ofinspiration are informal observations, practical problems, and previous research.
When coming up with a research question, three great resources for inspiration are informal observations, practical problems, and previous research.
two reasons that correlation does not imply causation
One reason why this does not work is because sometimes the relationship can go both ways. It is not one set variable that causes the other because each of the variables can result in the occurrence of the other. The other reason this does not work is because there is sometimes a third variable that is the cause.
“correlation does notnecessarily imply causation”
Just because a statistical relationship is present between two variables does not mean there is also a causal relationship present. Two variables being connected together does not necessarily mean that one of them caused the other to happen.
positive relationship
Positive relationship: when the score of one variable is high, so is the score of the other Negative relationship: when the score of one variable is high, the score of the other is low
difference between the mean scores of two groups on some variable of interest
This is a very common form of statistical relationships. This method is a head-to-head comparison of the data on tow groups with the same variable. This is used by comparing mean scores and standard deviations for each group.
There are two basic forms of statistical relationship: differences between groups and correlations between quantitative variables.
These are the two main forms of statistical relationships. It is used to learn about possible causes, consequences, development, and organisation of the behaviors
statistical relationship
Statistical relationship: when the average score on one variable differs systematically across the levels of the other one. This is what most research questions in psychology are about.
operationaldefinition
Operational definition: sets up how the variable is going to be measured within the research
One method of obtaining a sample
Sample: a group of people used to represent a larger group of people Random sampling: every member of the populations has an equal chance of being selected for the sample Convenience sampling: the sample consists of people who happen to be nearby and willing to participate
Research questions in scientific psychology are about variables
Variables are the basis for all research. They are the points of interest in any research. The variables are what the data is collected on.
empirically supported treatments
Empirically supported treatments: an empirically supported treatment is one that has been studied scientifically and shown to result in greater improvement than no treatment, a placebo, or some alternative treatment.

We know that students can show what they’ve learned in different ways, as mentioned above in terms of products produced as summative assessment.
In the same way that each student learns differently, every child has their own way of showing what they have learned. Because students are unique in these capacities, teachers should strive to adapt to these different styles. There are many students who have learned and understand a concept extremely well but are not good test takers. In this way, their knowledge cannot be accurately assessed. In order to ensure that each child has an accurate representation of their learning, it is crucial for teachers to incorporate a wide variety of learning assessments within their classroom.
Make sure to balance both so that you are supporting a collaborative environment while allowing time to meet students on an individual basis.
What amount of each element should a teacher have in their classroom? What makes a healthy balance between teamwork and self-sufficient learning?
From written components to artistic or theatrical, you can differentiate the ways that students are summatively assessed. Their passions actively come into play here.
Enabling students to use their creativity and passions in different way in the classroom makes their overall learning experience more enjoyable. Leaving a project more open ended when it comes what avenue is used to show the different required components creates a deeper connection between the child and their learning. Students could show their understanding of an assigned story's events by creating a skit, a video summary, or even a board game.
This is a great opportunity for them to set personalized learning goals and for you to target instruction specific to the goals they set.
This concept is gives students a great opportunity to take ownership of their learning. In situations like these, the student is able to focus on what they believe they could improve on. Because the student is the one who set the goal, they will likely be more motivated to learn and develop their skills in this area. Just like we saw with the "Learner-centered Psychological Principles," the more motivated a child feels to learn, the better their educational experience will be.
That way, I can take groups that need intensive work and ensure they are getting the instruction they need.
If teachers group students by academic ability, it allows each student to continue to grow in their education. Separating students with this method ensures that each student will become more skilled in that specific area, no matter where they are on the spectrum. The students who are at or above grade level in the area will continue to improve by receiving more challenging material. Likewise, students who are below grade level will improve to reach the grade level with appropriate material.
