Cerebral specialization and verbal-motor integration in adults with and without Down syndrome

Persons with Down syndrome (DS) tend to exhibit an atypical left ear-right hemisphere advantage (LEA) for the perception of speech sounds. In the present study, a recent adaptation of the dichotic listening procedure was employed to examine interhemispheric integration during the performance of a lateralized verbal-motor task. Although adults with DS (n = 13) demonstrated a right ear-left hemisphere advantage in the dichotic-motor task similar to their peers with (n = 14) and without undifferentiated developmental disabilities (n = 14), they showed an LEA in a free recall dichotic listening task. Based on a comparison of the laterality indices obtained from both dichotic listening procedures, it appears that the manifestation of lateral ear advantages in persons DS may dependent on the response requirements of the task.     

Compliance in crisis: Concern,trust and distrustful complacency in the COVID-19 pandemic

Two studies tested a distrustful complacency hypothesis, according to which either concern or political trust would be enough to sustain law-abiding attitudes and compliance with health-protective policies during the COVID-19 pandemic; but the absence of both concern and trust would result in markedly lower support and compliance. Study 1 supported this hypothesis with NatCen nationally representative sample of Great Britain (N = 2413; weighted regression analyses), focussing on law-abiding attitudes. Study 2 (preregistered) replicated these findings with a representative sample (N = 1523) investigating support for COVID-19 policies and compliant behaviour. Participants who were less concerned about the consequences of the pandemic (for themselves and for others) and simultaneously less trustful of the government expressed weaker law-abiding attitudes and reported less compliance with COVID-19 restrictions. These findings have implications for policy and public health strategies in time of crisis.     

Comments on the motivational status of self-esteem in social identity and intergroup discrimination

The background and development of motivational hypotheses in social identity theory are examined, revealing two general motives for intergroup discrimination: a desire for cognitive coherence, or good structure; and a need for positive self-esteem. The latter (self-esteem hypothesis: SEH) has received most attention. Both the theoretical and empirical bases of the SEH are largely rooted in research using the minimal group paradigm. However, it remains unclear whether self-esteem is to be considered primarily as a cause or an effect of discrimination. When real social groups are considered the SEH appears to provide only a partial explanation, and a variety of more or less powerful alternative social motives may underlie discriminatory behaviour. We explore some social-structural, individual and interpersonal limits to the SEH, and we call for an awareness of these motives and a re-examination of the good-structure thesis. The SEH, as it stands, provides only a partial contribution to our understanding of the relationship between social identity and discriminatory intergroup behaviour.     

Family work for schizophrenia: some issues for Chinese immigrant families

This paper discusses some specific issues relevant to immigrant Chinese families in the context of family work for schizophrenia. The issues include shame and guilt, isolation and mistrust of officials, the importance of negotiation before details of problem-solving are worked out, high academic ambitions for children, and apparent ‘overprotectiveness’ in the Chinese culture. It is argued that cognitive-behavioural, goal-orientated family work could be adapted well for immigrant Chinese families with a member suffering from schizophrenia. A case study is presented to illustrate how such a family was helped.     

Interrogative suggestibility: The effects of sleep deprivation and relationship with field dependence

Suggestibility (yield) scores on the first Gudjonsson Suggestibility Scale were found to correlate significantly with field dependence, as measured by the Finding Embedded Figures Test. Sleep-deprived subjects, while scoring worse on story memory, reaction time, POMS vigour–energetic and POMS confusion than controls, did not show any increase in yielding to suggestive questions. Upon answering the questions again after negative feedback, however, sleep-deprived subjects shifted their responses to questions significantly more than did controls. The results are interpreted in terms of sleep loss increasing the variability of performance.     

Art Media and the Sense Modalities: Tactile Pictures

It is widely assumed that the art media can be individuated with reference to the sense modalities. Different art media are perceived by means of different sense modalities, and this tells us what properties of each medium are aesthetically relevant. The case of pictures appears to fit this principle well, for pictures are deemed purely and paradigmatically visual representations. However, recent psychological studies show that congenitally and early blind people have the ability to interpret and make raised-line drawings through touch. This shows that pictures are not essentially visual representations. The view that pictures are essentially visual follows from influential views of the nature of depiction and of the nature of vision that are mistaken. By rooting out the mistake, we learn something about pictures, something about vision, and something about the doctrine that art media are individuated by the sense modalities.     

The Dysfunctional Attitude Scale: How well can it measure depressive thinking?

The Dysfunctional Attitude Scale (DAS) was designed to measure patterns of maladaptive thinking held by depressed individuals. Despite its wide use as a research and clinical tool, only a few studies to date were designed to examine its psychometric properties in a clinically depressed population. Moreover, problems of low sample size and limited tests of validity call these findings into question. The present study was designed to examine psychometric properties of the DAS in clinically depressed inpatients and in nondepressed clinical controls. Intertest correlations between the DAS parallel forms and between each form with total test scores ranged from r=.84 to r=.97. Intratest stability coefficients were r=.88 to r=.97. Support for the DAS as a valid measure of dysfunctional cognitions in depressed patients was also indicated. Of those scoring high on the DAS, 73% received an independent RDC diagnosis of clinical depression, while only 36% of those receiving low DAS scores were so diagnosed.     

Real-time speech synthesis

This paper describes how a speech synthesizer can be controlled by a small computer in real time. The synthesizer allows precise control of the speech output that is necessary for experimental purposes. The control information is computed in real time during synthesis in order to reduce data storage. The properties of the synthesizer and the control program are prsented along with an example of the speech synthesis.
