Basics The notions of word and word meaning are problematic to pin down, and this is reflected in the difficulties one encounters in defining the basic terminology of lexical semantics. Let us then elucidate the notion of word in a little more detail, and specify what key questions will guide our discussion of word meaning in the rest of the entry. On one side, we have linguistic definitions, which attempt to characterize the notion of word by illustrating the explanatory role words play or are expected to play in the context of a formal grammar. For example, words are the primary locus of stress and tone assignment, the basic domain of morphological conditions on affixation, clitization, compounding, and the theme of phonological and morphological processes of assimilation, vowel shift, metathesis, and reduplication Bromberger

Validity Firstly, what is validity? Validity refers to the extent to which findings or conclusions of a study are actually measuring what they claim to be measuring. So we get a tape measure and then proceed to measure the height of the table legs.

So, our measurement of the length of the table is invalid.

However, if we had intended to measure the height of the table, then our measurement would be valid, because we have measured the height of the table. Can you see an problem with this measurement? The problem is that the person with the stopwatch has to also react.

So, we would expect that this measurement is invalid. A better way to measure this dependent variable would be to use a video camera. Thus, making it more valid. Ecological validity and population validity. External validity refers to the extent to which the findings of a study can generalised.

It is important to have high levels of external validity because this directly affects the usefulness of the results and conclusions of the study.

Ecological Validity Ecological validity refers to the extent to which the results and conclusions are generalisable to real life. Ecological validity is mainly affected by the task which the participants have to do. Many people say that it is the methodology, for example, laboratory experiments, which affects the ecological validity, but this is not necessarily true.

It is possible to have a laboratory experiment which is high in ecological validity because the task that the participants have to do is true to real life.

Imagine that you are an experimenter and you are studying the psychology of shopping interactions with store clerks. You choose to use a laboratory experiment because it gives you better control over extraneous variables.

You set up a fake shop, which is exactly the same as in real life. You then have you participants go into the store and buy some items that they would normally buy. This, although a laboratory experiment, is high in ecological validity, because the task which the participants have to complete is true to real life.

This type of validity is important because without it the research becomes low in usefulness.

Suppose we are studying the impact of listening to Mozart on IQ the mozart effect. So we decide that we are going to use a sample of people with high IQs and we use a random sample.

This sample would have high population validity for people with high IQs, but mainly because we have used a random sample. However this sample would have low population validity for everyone else, because the sample is extremely limited.

Temporal Validity Temporal validity refers to the extent to which the findings and conclusions of study are valid when we consider the differences and progressions that come with time. However, a study into television advertising in the seventies and eighties may not be temporally valid today because of the many television channels available nowadays compared with the few channels that were available back then.

Take a look at this study for an example that can be considered low in temporal validity: This is the type of validity that you should refer to the least because it is not a very good evaluation point, internal validity would be a better type of validity to use.

Suppose we are trying to measure the effects of watching a scary movie on participant stress levels. We show our participants a scary movie and measure their cortisol levels before and after.

Therefore it has high face validity. However, we did not consider the impact of participants not eating when they were watching the film. We realise that not eating lowered our participants blood glucose levels, which also causes cortisol to be produced.

Test Validity Test validity is composed of several constituent parts.

Loftus and palmers Aims and context Loftus was concerned with how subsequent information could affect an eyewitness testimony (EWT) which is a legal term, referring to the use of eyewitness to give evidence in court. EWT can be influenced by misleading information in . This reference list was compiled by Robert Hare for personal use. Most, but not all, of the articles listed on these pages discuss or evaluate the PCL-R, the PCL:SV, the PCL:YV, and other Hare to available abstracts, and when available, links to the full text on the Journal web sites are provided (search for [full text] on the page below). This supports Loftus and Palmer’s findings as the study also changed the form of a question, which affected the witness’ response. Loftus and Palmer changed the verb ‘smashed’ and ‘hit’ to establish whether or not this would affect their answer.

Test validity refers to the extent to which the results of a study or test can be said to have meaning. Suppose we are measuring the intelligence of people. We might use an IQ test. We could argue than an IQ test has a high level of test validity because we can see that it is a well-established test.This supports Loftus and Palmer’s findings as the study also changed the form of a question, which affected the witness’ response.

Loftus and Palmer changed the verb ‘smashed’ and ‘hit’ to establish whether or not this would affect their answer.

Aim: To test their hypothesis that the language used in eyewitness testimony can alter memory..

Thus, they aimed to show that leading questions could distort eyewitness testimony accounts and so have a confabulating effect, as the account would become distorted by cues provided in the Saul Mcleod.
