Performance predictions affect attentional processes of event-based prospective memory

To investigate whether making performance predictions affects prospective memory (PM) processing, we asked one group of participants to predict their performance in a PM task embedded in an ongoing task and compared their performance with a control group that made no predictions. A third group gave not only PM predictions but also ongoing-task predictions. Exclusive PM predictions resulted in slower ongoing-task responding both in a nonfocal (Experiment 1) and in a focal (Experiment 2) PM task. Only in the nonfocal task was the additional slowing accompanied by improved PM performance. Even in the nonfocal task, however, was the correlation between ongoing-task speed and PM performance reduced after predictions, suggesting that the slowing was not completely functional for PM. Prediction-induced changes could be avoided by asking participants to additionally predict their performance in the ongoing task. In sum, the present findings substantiate a role of metamemory for attention-allocation strategies of PM.     

A Comparison of the TAT,CAT and CAT-H among Second Grade Girls

The TAT, CAT and CAT-H were administered to second grade girls and compared in terms of psychological usefulness on four dependent measures. The dependent measures were (a) Transcendence Index, (b) Word Count, (c) Response Organization and (d) Response Creativity. The results indicated that the CAT and CAT-H were more useful instruments for this age group.     

Face processing in autistics: Evidence for a generalised deficit?

Several studies have recently highlighted specific impairments in face processing in autistic subjects (memory for faces, recognition of emotional expressions, identity recognition of familiar faces). The goal of the present study was to explore whether there was a generalised face processing deficit in this population. A variety of tasks examining different, and possibly dissociative, aspects of face processing was investigated. The results of autistic subjects were compared with data from (a) a group of children with Down syndrome and (b) two individually matched control groups. The study suggests that autistic subjects are impaired in the various face processing tasks, but not always to the same extent.     

The perception of emotions by ear and by eye

Emotions are expressed in the voice as well as on the face. As a first step to explore the question of their integration, we used a bimodal perception situation modelled after the McGurk paradigm, in which varying degrees of discordance can be created between the affects expressed in a face and in a tone of voice. Experiment 1 showed that subjects can effectively combine information from the two sources, in that identification of the emotion in the face is biased in the direction of the simultaneously presented tone of voice. Experiment 2 showed that this effect occurs also under instructions to base the judgement exclusively on the face. Experiment 3 showed the reverse effect, a bias from the emotion in the face on judgement of the emotion in the voice. These results strongly suggest the existence of mandatory bidirectional links between affect detection structures in vision and audition.     

What aspects of face processing are impaired in developmental prosopagnosia?

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensive battery of well-established tasks. The tasks included measures of sensitivity to global motion and to global form, detection that a stimulus is a face, determination of its sex, holistic face processing, processing of face identity based on features, contour, and the spacing of features, and judgments of attractiveness. The DP cases showed normal sensitivity to global motion and global form and performed normally on our tests of face detection and holistic processing. On the other tasks, many DP cases were impaired but there was no systematic pattern. At least half showed deficits in processing of facial identity based on either the outer contour or spacing of the internal features, and/or on judgments of attractiveness. Three of the eight were impaired in processing facial identify based on the shape of internal features. The results show that DP is a heterogeneous condition and that impairment in recognizing faces cannot be predicted by poor performance on any one measure of face processing.     

Mechanisms underlying dependencies of performance on stimulus history in a two-alternative forced-choice task

In choice reaction time tasks, response times and error rates demonstrate differential dependencies on the identities of up to four stimuli preceding the current one. Although the general profile of reaction times and error rates, when plotted against the stimulus histories, may seem idiosyncratic, we show that it can result from simple underlying mechanisms that take account of the occurrence of stimulus repetitions and alternations. Employing a simple connectionist model of a two-alternative forcedchoice task, we explored various combinations of repetition and alternation detection schemes in an attempt to account for empirical results from the literature and from our own studies. We found that certain combinations of the repetition and the alternation schemes provided good fits to the data, suggesting that simple mechanisms may serve to explain the complicated but highly reproducible higher order dependencies of task performance on stimulus history.     

Lexical access of resyllabified words: Evidence from phoneme monitoring

Resyllabification is a phonological process in which consonants are attached to syllables other than those from which they originally came. In four experiments, we investigated whether resyllabified words, such as "my bike is" pronounced as "mai.bai.kis," are more difficult to recognize than nonresyllabified words. Using a phoneme-monitoring task, we found that phonemes in resyllabified words were detected more slowly than those in nonresyllabified words. This difference increased when recognition of the carrier word was made more difficult. Acoustic differences between the target words themselves could not account for the results, because cross-splicing the resyllabified and nonresyllabified carrier words did not change the pattern. However, when nonwords were used as carriers, the effect disappeared. It is concluded that resyllabification increases the lexical-processing demands, which then interfere with phoneme monitoring.     

Marital discord and childhood behavior problems

Measures of overt marital hostility, general marital adjustment, and children's behavior problems were obtained from the parents of 64 children referred to a child psychological clinic. Correlations between children's scores on measures of general marital unhappiness and overt marital hostility were compared. Overt marital hostility correlated significantly with many behavior problems of boys. However, neither general marital unhappiness nor overt marital hostility related to problem behaviors in girls. Specific findings and possible reasons for the differential results with respect to boys and girls were discussed.Special thanks to Robert Emery for his expertise regarding the analysis of our data.     

Learning at the workplace and sustainable employability: a multi-source model moderated by age

This study, among 330 pairs of employees and their supervisors, tested whether self- versus supervisor ratings of five employability dimensions (occupational expertise, corporate sense, personal flexibility, anticipation and optimization, and balance) are associated with different learning characteristics in the workplace, and whether age moderates these relationships. Results of structural equation modelling showed that the learning value of the job positively related to both self- and supervisor ratings of corporate sense, personal flexibility, and anticipation and optimization. Applicability in the job of recently followed training and development programmes was associated with all dimensions of self-rated employability and with supervisor ratings of anticipation and optimization. Regarding the hypothesized age moderation effects, contrary to our expectations, it was found that both learning value and applicability of training and development related more strongly to self-rated anticipation and optimization for younger workers. In addition, age appeared to moderate the otherwise non-significant relationship between learning value and self-rated occupational expertise. Implications for Human Resource Development (HRD) practices are discussed. As learning characteristics are differentially related to the unique employability dimensions, tailor-made development programmes are key. Moreover, it is advocated that having a job with a high learning value is an important factor in the light of the employee’s sustainable employability.
