Individual-differences assessment of the relationship between change in and initial level of adult cognitive functioning

Methodological factors may have been partially responsible for the inconsistency in findings from previous investigations into the relationship between change in, and initial level of, adult cognitive functioning. An alternative data-analytic procedure is proposed and applied to data from 277 men (25-76 years of age at initial testing) over 3 measurement occasions (interwave intervals of 6.7 years). Performances on both the Benton Revised Visual Retention Test (BVRT) and the Wechsler Adult Intelligence Scale (WAIS) Vocabulary subtest were analyzed. The findings demonstrate that the significant negative relationships between change and initial status, found on both tests, were partially a function of measurement error. Once adjustments were made for errors of measurement, the previously significant negative relationship for the BVRT data became significantly positive, whereas for the WAIS the relationship remained significantly negative, although to a lesser degree. The importance of accounting for errors of measurement is discussed.     

The role of cognitive stimulation on the relations between age and cognitive functioning

To make a convincing argument that cognitive stimulation moderates age trends in cognition there must be (a) a negative relation between age and level of cognitive stimulation, (b) a positive relation between level of cognitive stimulation and level of cognitive functioning, and (c) evidence of an interaction between age and cognitive stimulation in the prediction of cognitive functioning. These conditions were investigated in a study in which 204 adults between 20 and 91 years of age completed an activity inventory and performed a variety of cognitive tasks. Only the 1st condition received empirical support, and, thus, the results of this study provide little evidence for the hypothesis that cognitive stimulation preserves or enhances cognitive functioning that would otherwise decline.     

On the validity of hypotheses derived from the Rorschach: V. The relationship between form level and ego strength.

Although Rorschach interpreted from level as a perceptual and conceptual aspect of intelligence, Beck and the more current meaning assigned to form level relates these functions to ego strength. F+%, therefore, has come to be regarded as a measure of ego strength. The research examining the validity of this assumption was reviewed and Beck's hypothesis was seen to be supported. The research supports the clinical use of F+% as a measure of ego strength, but further research might help clarify what actual psychological processes are involved in the creation of responses of good form.     

Contributions of cognitive science to the Rorschach Technique: cognitive and neuropsychological correlates of the response process

This article presents an understanding of the Rorschach Technique in terms of emergent models from cognitive science. We propose a linkage between cognitive psychology and neuropsychology in understanding the operations that underlie the Rorschach response process. Contemporary information processing models are described. The Rorschach Technique is conceived of as a complex process involving all areas of the cerebral hemispheres, encompassing various aspects of visual attention and perception, object recognition, associative memory, language production, and executive functioning. Exner's model of the response process is delineated, including both Association and Inquiry phases, in terms of requisite underlying neuropsychological abilities and anatomical substrates. The question of the Rorschach Technique's status, utility, and potential as a neuropsychological assessment, tool is discussed. Understanding the Rorschach in terms of contemporary cognitive psychological and neuropsychological models heightens appreciation of the technique's complexity and provides a heuristic and conceptual foundation for empirical research.     

The influence of gender, handedness, and performance level on specialized cognitive functioning

Individual differences in performance on neuropsychological tests were analyzed across age (prepubertal to adult), gender, and handedness groups and examined for performance level as a moderating variable. No differences were observed for the factor structure of these tests across ages and between genders, suggesting similar cognitive structures among these groups. Significant differences in performance were observed between males and females and, to a lesser extent, between right and left handers. Of interest, were significant Gender x Handedness and Gender x Handedness x Level (of performance) interactions seen especially in the older (postpubertal and adult) subjects. High performing, right handed males and left handed females performed better on visuospatial tasks while left handed males and right handed females performed better on verbosequential tasks.     

The relationship between cognitive inhibition and psychotic symptoms

Cognitive models of schizophrenia have highlighted deficits of inhibitory attentional processes as central to the disorder. This has been investigated using "negative priming" (S. P. Tipper, 1985), with schizophrenia patients showing a reduction of negative priming in a number of studies. This study attempted to replicate these findings, but studied psychotic symptoms rather than the broad diagnostic category of schizophrenia. Psychotic individuals exhibiting positive symptoms were compared with asymptomatic psychiatric patients and with a normal control group. As predicted, the symptomatic group failed to show the usual negative priming effect, which was present in the asymptomatic and normal groups. A modest but significant correlation was found between negative priming and delusions. Neither diagnosis, nor affective or negative symptoms, nor chronicity, nor medication, was related to negative priming. These data replicate previous findings that positive symptoms are related to a reduction in cognitive inhibition, although considerable variability was observed among the psychotic patients.     

The relationship between cognitive dissonance and helping behavior

An experiment was conducted to study the relationship between cognitive dissonance and helping behavior. A counterattitudinal procedure was employed to arouse dissonance. For half of the participants, an experimental confederate entered the room and elicited an opportunity for them to offer help. In this situation, fewer subjects in the dissonance condition offered help than subjects in the no‐dissonance condition. The least helping occurred among dissonance subjects with the highest level of commitment to the counterattitudinal task. Those with a medium level of commitment offered significantly more help. Despite the fact that results in line with Festinger's cognitive dissonance theory (subjects' attitudinal change) were obtained in the no‐helping situation, in helping situations, dissonance subjects who offered help presented significantly less attitude change than those who did not offer it. This was considered to be a result of helpfulness reducing dissonance arousal.     

The validity of the Rorschach for assessing cognitive and affective changes

Exner's (1985) Rorschach norms of children 5 to 16 years old were used to test predictions based on developmental theory, previous cognitive studies, and Achenbach and Edelbrock's (1981) norms on behavior problems in children. In the cognitive realm, the Rorschach scores reflected the predicted increase in complexity, integration, and precision of thinking; richness of ideas; conformity to socially acceptable ways of thinking; and the concomitant decrease in unrealistic, egocentric ideas. In the affective realm, the Rorschach scores reflected the predicted decrease in uncontrolled expression of affect, increase in controlled expression of affect, and increase in inwardness. However, the Rorschach scores failed to reflect the predicted decrease in anxiety and increase in depression. Finally, there was no evidence of increased accuracy of perception.     

The relationship between face recognition ability and socioemotional functioning throughout adulthood

The relationship between face recognition ability and socioemotional functioning has been widely explored. However, how aging modulates this association regarding both objective performance and subjective-perception is still neglected. Participants, aged between 18 and 81 years, performed a face memory test and completed subjective face recognition and socioemotional questionnaires. General and social anxiety, and neuroticism traits account for the individual variation in face recognition abilities during adulthood. Aging modulates these relationships because as they age, individuals that present a higher level of these traits also show low-level face recognition ability. Intriguingly, the association between depression and face recognition abilities is evident with increasing age. Overall, the present results emphasize the importance of embedding face metacognition measurement into the context of these studies and suggest that aging is an important factor to be considered, which seems to contribute to the relationship between socioemotional and face-cognitive functioning.     

The relationship between executive functioning and self-regulated learning in Australian children

Executive functioning (EF) and self-regulated learning (SRL) are established predictors of academic achievement, both concurrent and future. Although it has been theorized that EF development enables SRL in early childhood, this directional model remains empirically untested against plausible alternatives. Thus, this study investigated the longitudinal relations between children’s EF and SRL during the transition from kindergarten to Year 1 in an Australian sample to determine the direction and strength of the association between EF and SRL. We compared four directional models and also tested whether EF and SRL can be construed as manifestations of a common factor. Children’s EF was assessed using a battery of tasks tapping working memory, inhibition, and shifting, and their SRL was assessed by teachers using the Checklist of Independent Learning Development. Cross-lagged structural equation modelling analyses were conducted on a longitudinal dataset of 176 children at the end of kindergarten (age M = 5 years, 8 months; SD = 4.02 months), and 1 year later (age M = 6 years, 5 months; SD = 3.65 months). EF predicted SRL longitudinally (β= .58, controlling for kindergarten SRL), consistent with common assumptions, whereas SRL did not predict EF. However, the common factor model also fit the data very well. We concluded that EF and SRL are indeed related concurrently and longitudinally but that further evidence is needed to disambiguate whether EF is best understood as a necessary antecedent of SRL development in early childhood, or whether they reflect the same general construct.     

The relationship between formal thought disorder and executive functioning component processes

In 2 studies, associations between formal thought disorder (FTD) and 2 components of executive functioning, processing of context and interference resolution, were investigated. One study, involving people with schizophrenia, examined associations between performance on processing of context (N-back) and interference resolution (interference in Steinberg probe recognition) tasks and FTD. The second study, involving nonpsychiatric participants, was an analogue study that examined the effects of simulated processing of context (performance of 1-back with distraction) and interference resolution (telling new stories about previously seen pictures) deficits on FTD in a speech production task. In both studies, processing of context deficits predicted FTD. Moreover, in both studies, the effect of processing of context deficits on FTD was especially pronounced when combined with interference resolution deficits.     

The relationship between speed of information processing and cognitive ability

Speed of information processing as measured by various reaction time and inspection tasks has been shown to correlate with psychometric intelligence, and it has been suggested that general intelligence (g) is determined to some degree by the speed that information is processed. If this is so, then various measures of speed of information processing should correlate substantially with each other, and each should also correlate with a wide range of psychometric tests that load on g. Alternatively, intelligence may be considered to be a multi-faceted complex of partially related abilities with specific abilities being dependent upon specific cognitive processes. If this is the case, it should be possible to discover independent cognitive processes, some of which correlate with one facet or broad ability and some with another. This paper presents three experiments in which the relationship between intellectual ability and four speed of information processing measures was examined. These were rate of memory scanning, rate of retrieval of information from long term memory, speed of stimulus-response mapping and inspection time (IT). Results showed that correlations between IT and most reaction time measures of speed of information processing were low, and that correlations between different versions of IT were negligible. In addition, some cognitive tasks with verbal material (memory scanning rate for digits and Posner letter matching IT) correlated most substantially with Verbal Reasoning whereas non-verbal (two-line) IT consistently correlated with tests loading on g. It was thus suggested that while non-verbal IT may be a measure of a perceptual speed attribute that contributes to mental functioning, other “speed of information processing” parameters may be more specific to a subset of abilities.
