WASI profile variability in a sample of psychiatric inpatients

This study examined the variability of Wechsler Abbreviated Scale of Intelligence profiles using the subtest range and profile variability index in a sample of 70 psychiatric inpatients. The subtest range and profile variability index were correlated .93 (p<.001), indicating that either measure may be used to assess profile variance. Comparison of profile variability on this abbreviated scale with other Wechsler intelligence scales in similar populations suggests that variability measures are not comparable across the tests.     

Psychological correlates of optimism in college students

This study assessed optimism held by 300 college students at a midwestern university using Scheier and Carver's Life Orientation Test. Optimism ratings were compared to measures of psychological functioning. Analysis showed that optimism was significantly associated with all of the adjustment measures (social, academic, personal, and goal commitment) assessed with Baker and Siryk's Student Adaptation to College Questionnaire, higher self-esteem measured with Rosenberg's Self-esteem scale, and with lower ratings of loneliness as assessed with the Revised UCLA Loneliness Scale.     

Real-Time Processing Implications of Enriched Composition at the Syntax–Semantics Interface

This study reports results on the real-time consequences of aspectual coercion. We define aspectual coercion as a combinatorial semantic operation requiring computation over and above that provided by combining lexical items through expected syntactic processes. An experiment is described assessing whether or not parsing of a string requiring coercion—in addition to syntactic composition—is more computationally costly than parsing a syntactically transparent counterpart, a string that provides for an interpretable representation via syntactic composition alone. The prediction of a higher computational cost for this process is borne out by the results.     

On Not Seeing What You Do Not Want to See: Meloen, van der Linden and de Witte on Authoritarianism

Meloen, van der Linden, and de Witte (1996) were puzzled by their finding that their various scales of authoritarian attitudes all correlated at similar low levels with approval for a racist political party. They also reported that the "Directiveness" behavior inventory correlated not at all with political variables. If the validity characteristics of the various scales used are taken into account, however, the implications of their results are clear: The alleged scales of authoritarian attitudes were simply functioning as alternative scales of conservatism and people who preferred leftist political parties were just as likely to be authoritarian as those who preferred racist political parties.     

Knowing what to remember and forget: A developmental study of cue memory in intentional forgetting

These experiments are the first to investigate children’s encoding and use of information about a memory cue in Bjork’s (1972) intentional forgetting task. In Experiment 1, children in Grades 2, 4, and 6 and college students were given cues to either remember or forget after the presentation of each picture. Recall and recognition tests of pictures and cues followed. The procedure in Experiment 2 was identical to that in Experiment 1 except that the list of presentation pictures was altered for some children (Grades 3 and 4) and adolescents (Grades 8 and 9) so that remember and forget cues were associated with particular taxonomic categories. In Experiment 3, the testing component was modified so that children (Grades 2, 3, and 4) and college students were asked to recall only the cue associated with each picture. The results indicated that (1) children as young as second graders encode the cue associated with each picture, although to a lesser extent than do college students, (2) much improvement in intentional forgetting is still occurring during adolescence, (3) only adults adequately cluster their recall by cue, (4) associating remember and forget cues with items from different categories does not increase the differentiation between cues, and (5) eliminating picture recall and recognition has minimal effects on the magnitude of cue judgments. These results suggest that children’s difficulties on intentional forgetting tasks stem, at least in part, from their poorer encoding of information about whether an item should be remembered or forgotten.     

Pupil dilation, sex of stimulus, and age and sex of observer

10-yr.-old, 16-yr.-old, and 20-yr.-old male and female observers (ns = 10; N = 60) rated a number of male and female faces for how 'good-looking' they were. Some of these faces were identical save that in one version the pupils were larger. Pupil dilation in the photographs of males produced no significant effects, whereas pupil dilation in the female photographs caused such faces to be rated as more good-looking by the two oldest groups of male observers. The 10-yr.-old boys and the 16- and 20-yr.-old women rated the female faces with enlarged pupils as significantly less 'good-looking' than the same faces with smaller pupils.     

Authoritarianism, dominance and assertiveness

It is shown that there are definitions of the three constructs of authoritarianism, dominance and assertiveness which read very similarly; so much so that no distinction is immediately evident. It is proposed that authoritarianism might be conceived as aggressive dominance and at least some types of assertiveness as nonaggressive dominance. A new scale of Dominance suitable for general population use was produced, and compared with the existing Ray (1976) behavior inventory of authoritarianism. Both scales showed highly significant correlations with peer rated dominance and submission (the latter being negative in sign) but only the authoritarianism scale showed significant correlations with rated aggressiveness and rigidity. It was concluded that the new definitions could be operationalized into valid scales.     

A multiple-observations model for response latency and the latencies of correct and incorrect responses in recognition memory

A model for response latency in recognition memory is described which is a strength model incorporating the notion of multiple observations and with the additional assumptions that the variance of the strength distributions increase with set size and that the observer attempts to keep his error rate at a constant level over set size. It is shown that the model can, without recourse to particular parameter values, predict a near linear RT set-size function and, since it is a (TSD) model in its decision aspects, can account for errors and hence error latencies in the recognition task. After the model is described, two experiments are performed which test the prediction that correct mean latency is generally shorter than incorrect mean latency. The prediction is confirmed and this feature is discussed in general, the model being compared with that of Juola, Fischler, Wood, and Atkinson (1971) in this respect. Some possible modifications to the latter model are also considered.
