Commitment to “Safer” Sex as a Predictor of Condom Use Among 16-20-Year-Olds1

The AIDS risk reduction model (ARRM) is explored in the context of a prospective study of adolescent condom use. This three-stage model characterizes the social and psychological facilitation of change in attitudes and sexual behaviors related to HIV transmission. The social and behavioral consequences of AIDS for 63 adolescents (aged 16-20 years), from an urban part of North West London, were mapped over a one-year period. Indices were created according to the proposed model which reflect (a) labelling of a high risk behavior as problematic (e.g., unprotected sexual intercourse) (b) commitment to change (e.g., desiring and valuing “safe” sex), and (c) seeking and enacting appropriate solutions (e.g., use of condoms). Nested regression analysis enabled the inter-relationship between significant social and psychological predictors (Time 1) and behavior (Time 2) to be traced. Overall the model accounted for 30% of the variance in condom use. Contemporaneous behavior was also modeled to identify baseline social and psychological predictors. Twenty-seven percent of the variance in condom use is explained. The social and psychological patterning of the indices is compared with that evidenced for prospective behavior. It appears that social representations which embody normative and value considerations underlie commitment to safer sex (at a general level) and override intentions (at a specific level) in the explanation of prospective behavior. The methodological and theoretical implications of this are identified and discussed.     

Memory in educable mentally retarded adults: Deficit in subject or experimenter?

Educable mentally retarded (EMR) and nonretarded adults free recalled lists of (a) words, (b) minitasks performed by the subjects (SPTs), (c) minitasks performed by the experimenter (EPTs), or (d) task instructions. The EMR subjects were significantly inferior to the nonretarded subjects in the immediate recall of words, EPTs and instructions, but not in the immediate recall of SPTs. This proficiency of the EMR subjects in SPT recall was attributed to the nonstrategic nature of this test. The EMR subjects were, however, inferior to the nonretarded subjects in a final free recall (recall of all lists) of all four types of item.     

Ethnic differences in illness perceptions,self-efficacy and diabetes self-care

This study assessed differences between Europeans, South Asians and Pacific Islanders in illness perceptions, self-efficacy, self-care, metabolic control and retinopathy in diabetes. We also evaluated the role of illness perceptions and self-efficacy in diabetes self-care and metabolic control within each group. A total of 86 Europeans, 86 South Asians, and 87 Pacific Islanders with type-2 diabetes completed self-report measures of illness perceptions, self-efficacy and self-care. Metabolic control and retinopathy data were collected from patient records. Results showed that Pacific Islanders and South Asians held shorter illness timeline perceptions compared to Europeans. Relative to both the other groups, Pacific Islanders also had elevated scores on three illness perceptions subscales: consequences, identity and emotional representations. They had lower medication-specific self-efficacy as well as poorer medication self-care, metabolic control and retinopathy. In all three groups, self-efficacy was fairly consistently related to self-care, but not to metabolic control. Illness perceptions were less consistently related to self-care, but were associated with metabolic control.     

Receptive vocabulary and semantic knowledge in children with SLI and children with Down syndrome

Receptive vocabulary and associated semantic knowledge were compared within and between groups of children with specific language impairment (SLI), children with Down syndrome (DS), and typically developing children. To overcome the potential confounding effects of speech or language difficulties on verbal tests of semantic knowledge, a novel task was devised based on picture-based semantic association tests used to assess adult patients with semantic dementia. Receptive vocabulary, measured by word-picture matching, of children with SLI was weak relative to chronological age and to nonverbal mental age but their semantic knowledge, probed across the same lexical items, did not differ significantly from that of vocabulary-matched typically developing children. By contrast, although receptive vocabulary of children with DS was a relative strength compared to nonverbal cognitive abilities (p < .0001), DS was associated with a significant deficit in semantic knowledge (p < .0001) indicative of dissociation between word-picture matching vocabulary and depth of semantic knowledge. Overall, these data challenge the integrity of semantic-conceptual development in DS and imply that contemporary theories of semantic cognition should also seek to incorporate evidence from atypical conceptual development.     

Executive function, intellectual decline and daily living skills

Understanding the cognitive changes associated with compromised daily living skills in elderly individuals is important for making appropriate recommendations about the capacity for independent functioning. To this end, we retrospectively examined data from 92 elderly individuals presenting with cognitive decline who were administered measures of executive functioning, general intelligence, and daily living skills. Multiple regression analyses were used to examine the relationship between executive functioning and daily living skills, while controlling for age, depression, and either IQ decline or current IQ. Executive functioning accounted for additional variance in a broad range of daily living skills after controlling for IQ decline. When FSIQ was used in the regression model rather than IQ decline, executive functioning was no longer uniquely associated with daily living skills. Executive functions appear to be important for daily living skills until a critical threshold of low intellectual functioning is reached, reflecting the combined influence of premorbid ability and the extent of intellectual decline. Our results suggest that understanding the relative contribution of different cognitive domains to functional decline in elderly individuals should take into account general intellectual functioning and estimated decline, and that the initiation and/or persistence of self-directed cognitive processes may be important for adaptive daily functioning. These findings have implications for making more evidence-based recommendations about the capacity for independent living.     

A comparison of different investigative interviewing techniques in generating differential recall enhancement and detecting deception

This study compared the Stepwise Interview, Cognitive Interview, and Reality Interview in detecting deception with inmates. The dependent measures were the amount of unique details provided during the free narrative and mnemonics and the number of words provided during the free narrative and mnemonics of each interview. The Stepwise Interview generated 58.3% accuracy, the Cognitive Interview generated 70.0% accuracy, and the Reality Interview generated 93.3% accuracy. The different tasks of these interviews increased the differences between honest and deceptive statements and therefore, increased the accuracy in detection of deception. Differential recall enhancement is used to explain the findings.     

Perceptual learning with a sodium depletion procedure

Rats in a state of salt need prefer a flavor that has previously been paired with saline (Experiment 1). In Experiments 2 and 3, rats exposed to 2 saline concentrations, presented either concurrently or on separate trials, and each paired with a different flavor, showed a preference for the flavor that had been associated with the stronger saline. This effect was substantial, however, only in those rats that had experienced the concurrent exposure schedule. This effect cannot be attributed to a difference in the strength of within-compound associations produced by the 2 preexposure schedules (Experiment 4). It is suggested that concurrent preexposure can engage a learning process that enhances the discriminability of the preexposed stimuli.     

Self‐Reported Beliefs About Verbal Cues Correlate with Deception‐Detection Performance

In this study, we investigated whether people who hold more correct beliefs about verbal cues to deception are also better lie detectors. We investigated police officers and undergraduates' beliefs about (i) cues to deception via an open‐ended question and (ii) 17 specific verbal cues, after which participants were asked to judge the truthfulness of eight video fragments. Results showed that undergraduates and police officers still hold wrongful beliefs about nonverbal cues, but have better insight into verbal cues. Moreover, a better insight in verbal cues was related to an increased accuracy for identifying truthful statements, showing that verbal cues do drive credibility judgments to some extent.Copyright © 2017 John Wiley & Sons, Ltd.     

Stereotypical behavioural cues — but not their order — influence credibility judgements

To what extent stereotypical deceptive behaviours such as gaze aversion and fidgeting actually influence people's credibility judgements remain largely unknown. In this study, we directly manipulated the presence/absence of such behaviours to investigate this. Participants were shown four truthful videos in which we manipulated the presence of stereotypical cues and asked them to judge how credible the person in each video is. Moreover, research consistently shows that decision making is influenced by various cognitive biases. One example is the primacy effect, which implies that people form an opinion early in the decision process. Information acquired early will have the largest influence on how subsequent information will be interpreted. To investigate a possible primacy effect, we also manipulated whether these cues were present towards the beginning or the end of the video (i.e. the timing of the manipulation). In line with our expectations, the presence of stereotypical cues significantly lowered the observed credibility, showing that the presence of these cues indeed influences credibility judgements. The timing of the cues had no effect.
