The Self‐Administered Witness Interview Tool (SAW‐IT): Enhancing witness recall of workplace incidents

Given the often crucial role of witness evidence in occupational health and safety investigation, statements should be obtained as soon as possible after an incident using best practice methods. The present research systematically tested the efficacy of a novel Self‐Administered Witness Interview Tool (SAW‐IT), an adapted version of the Self‐Administered Interview designed to elicit comprehensive information from witnesses to industrial events. The present study also examined the effect of schematic processing on witness recall. Results indicate that the SAW‐IT elicited significantly more correct details, as well as more precise information than a traditional incident report form. Contextual information about a worker's safety history biased the reports of participant witnesses, confirming that witnesses should be shielded from extraneous post‐event information prior to reporting. Importantly, these results demonstrate that the SAW‐IT can enhance the quality of witness reports.     

An experimental examination of the effects of alcohol consumption and exposure to misleading postevent information on remembering a hypothetical rape scenario

We experimentally examined the effects of alcohol consumption and exposure to misleading postevent information on memory for a hypothetical interactive rape scenario. We used a 2 beverage (alcohol vs. tonic water) × 2 expectancy (told alcohol vs. told tonic) factorial design. Participants (N = 80) were randomly assigned to conditions. They consumed alcohol (mean blood alcohol content = 0.06%) or tonic water before engaging in the scenario. Alcohol expectancy was controlled by telling participants they were consuming alcohol or tonic water alone, irrespective of the actual beverage they were consuming. Approximately a week later, participants were exposed to a misleading postevent narrative and then recalled the scenario and took a recognition test. Participants who were told that they had consumed alcohol rather than tonic reported fewer correct details, but they were no more likely to report incorrect or misleading information. The confidence–accuracy relationship for control and misled items was similar across groups, and there was some evidence that metacognitive discrimination was better for participants who were told that they had consumed alcohol compared with those told they had tonic water. Implications for interviewing rape victims are discussed.     

Significant and other: systemic family therapists on lesbians and gay men

This paper discusses a questionnaire survey done with a sample of 130 systemic family therapists, which investigated their training in, and experience of, working with lesbian and gay male clients and attitudes towards lesbians and gay men using the Index of Attitudes to Homosexuals. The findings indicate that the majority of respondents had received relatively little training in working with this client group within their systemic training. It also indicated that their attitudes towards lesbians and gay men generally may have been influenced by the degree of social, professional or familial contact that they had with them.     

Colored-Speech Synaesthesia Is Triggered by Multisensory, Not Unisensory, Perception

ABSTRACT— Although it is estimated that as many as 4% of people experience some form of enhanced cross talk between (or within) the senses, known as synaesthesia, very little is understood about the level of information processing required to induce a synaesthetic experience. In work presented here, we used a well-known multisensory illusion called the McGurk effect to show that synaesthesia is driven by late, perceptual processing, rather than early, unisensory processing. Specifically, we tested 9 linguistic-color synaesthetes and found that the colors induced by spoken words are related to what is perceived (i.e., the illusory combination of audio and visual inputs) and not to the auditory component alone. Our findings indicate that color-speech synaesthesia is triggered only when a significant amount of information processing has occurred and that early sensory activation is not directly linked to the synaesthetic experience.     

Decision-Making About Inherited Cancer Risk: Exploring Dimensions of Genetic Responsibility

Since genetic information has implications for family members, some choices about genetic risk may be influenced by perceptions of responsibility to relatives. Drawing upon 25 semi-structured interviews with test recipients in Canada, this study explored decisions about inherited breast-ovarian and colon cancer. Qualitative data analysis revealed the pervasive significance of genetic responsibility in test decisions. We highlight three dimensions of genetic responsibility: 1) to know about the self for self; 2) to know about the self for others; 3) to know about the self to oblige others to know. It is argued that these dimensions of genetic responsibility have implications for test decisions, family relationships and other family members’ desire to know (or not know) and to act (or not act) with respect to their own genetic risk. In particular, genetic responsibility may play out as a framing of a relative’s moral obligation to know their risk that could obviate any interest they might have in not knowing. We conclude that perceptions of responsibility to—and of−other family members be thoroughly explored in genetic counseling sessions.     

A respectable job: Factors which influence young Asians' choice of career

To find out why some college or university courses are particularly attractive to ethnic-minority school-leavers, school pupils and first-year students of South Asian (n=158) and UK origin (n = 158) completed a questionnaire relating to occupational choice. The social position attainable from a 'respected' profession and the ability to work with others who share similar beliefs were found to be of greater importance to subjects from an Asian background than to those of UK origin, who placed greater emphasis on personal growth and autonomy. There was no evidence that the Asian young people were consciously choosing careers with the aim of avoiding discrimination.     

THE LOGICAL PROBLEM OF LANGUAGE ACQUISITION

Arguments from the Logical Problem of Language Acquisition suggest that since linguistic experience provides few negative data that would falsify overgeneral grammatical hypotheses, innate knowledge of the principles of Universal Grammar must constrain learners hypothesis formulation. Although this argument indicates a need for domain-specific constraints, it does not support their innateness. Learning from mostly positive data proceeds unproblematically in virtually all domains. Since not every domain can plausibly be accorded its own special faculty, the probative value of the argument in the linguistic case is dubious. In ignoring the holistic and probablistic nature of theory construction, the argument underestimates the extent to which positive data can supply negative evidence and hence overestimates the intractability of language learning in the absence of a dedicated faculty. While nativism about language remains compelling, the alleged Logical Problem contributes nothing to its plausibility and the emphasis on the Problem in the recent acquisition literature has been a mistake.     

Pupils as consumers: Perceptions of guidance and counselling in a scottish school

Pupils' perceptions' of the effectiveness of counselling services were investigated within a school with a high degree of commitment to guidance and counselling. Pupils were asked to read eight problems: four were school-based, and four were personal/familial problems. Half the sample were given a list of possible sources of assistance (including counselling staff); half were unprompted On personal and familial problems, the unprompted group were as likely to cite counsellors as being sources of assistance as were the group prompted with the names of counselling staff. This was taken as an indication that counselling staff were spontaneously seen as sources of help on these matters. In addition, respondents completed semantic-differential protocols, analyses of which indicated that counselling staff were seen in more pastoral terms than were other teaching staff. These results are discussed within a perspective that sees the school's guidance and counselling system as interacting with its general ethos.     

On the detection of stepwise changes in a constant signal level

A stepwise change in the frequency of a continuous pure tone is taken as an element signal. The detectability of a single step is compared with the detectability of a pattern composed of two such steps in order to determine the ways in which the steps interact and how these interactions depend upon the time interval between the steps. It is shown that two positive steps separated by D msec interact by summation (d’ for two steps being greater than d’ for a single step) and that this summation is 100% even when D=100 msec. The extent of summation decreases as D is increased beyond 100 msec, leveling off at about 40% when D is near 1,000 msec. A positive step followed by a negative step (an increment) presents a more complex picture. When D=0 msec, the pattern is the null signal, and, of course, the two steps subtract completely. As D is increased, the extent of subtraction decreases, becoming zero when D is about 400 msec. Increasing D beyond 400 msec results in summation, reaching about 40% when D=2,000 msec. For D less than about 1,000 msec, the sign of the second step in a two-step signal is important: two steps of like sign summate, and two steps of unlike sign subtract. However, when the two steps are separated by about 2,000 msec, the sign of the second step is irrelevant: summation occurs, and the extent, about 40%, is the same for two steps of like sign and two steps of unlike sign. A brief theoretical discussion stresses the extant need for an information-processing theory of signal detection.
