A remote keyboard switch for the IBM PC/AT and compatibles

A relatively simple, remote keyboard switch for the IBM PC/AT and compatibles is discussed. It may be used to isolate a subject from an experimenter when the experimenter is controlling an experiment with the PC. The device, based on a 4066 CMOS, when used in conjunction with a monochrome monitor and a color monitor, enables the experimenter to switch, manually or programmatically (TTL), between the local monitor and the local keyboard and a remote monitor and a remote keyboard for presentation of stimuli and for recording of subject’s responses.     

Determination of health-care workers' attitudes toward people with AIDS

One hundred and thirty-four health professionals read one of 12 fictional case histories in which the patient was diagnosed as being either HIV- or Hepatitis B-positive. For each diagnosis infection was attributed to sexual contact, IV drug use, or a transfusion of contaminated blood. Within each diagnostic category, and for each source of infection, the patient was identified as either heterosexual or homosexual. Although homophobia has been suggested as a major contributor to negative attitudes toward people with AIDS, the present results remained significant even after homophobia, as measured by Hudson and Ricketts (1980), had been controlled for statistically. Regardless of disease, patients infected through IV drug use or sexual contact were seen as equally culpable and more responsible for their condition than those infected by transfusion. HIV, but not Hepatitis B, patients infected by sex or IV drug use were perceived as having less moral integrity than those infected by transfusion. Source of infection also influenced respondents' desire for close personal interaction. Negativity toward particular patient groups based merely on information about patient lifestyles was clearly demonstrated and it is suggested that negative attitudes toward people with AIDS may be a reflection of negative attitudes toward sexuality generally, rather than homosexuality.     

Persons and organisms

The philosophical quest for unity leads to the desire for a clear and adequate conception of human reality as a “mind-body unity.” This quest for unity has led both to conceptions of considerable heuristic value and to overly reductionistic approaches that impoverish our full relation to reality. Three basic themes are developed in this essay:

1. That on an ontological level dualistic and monistic approaches to mind-body remain equally plausible.
2. That on a practical level, epistemological considerations require us to retain a dualistic approach suggested by the terms “person” and “organism.”
3. That psychotherapy (whether religious or secular) must ground itself in the notion of “person.”

Differences between the concepts of “person” and “organism” are delineated on six specific points. Finally, it is suggested that a holistic approach to health requires both constructs.     

Tactile-kinaesthetic perception of straightness in blind and sighted humans

A comparison is made between the tactile-kinaesthetic perception of straightness in twenty blind and twenty sighted subjects. Both types of subject are found to perceive a “plus curved” edge as straight, but this curve is significantly less for the blind than for the sighted, i.e. the blind subjects' judgments correspond more closely to the objective straight. Furthermore, the blind, both as individuals and as a group, are significantly finer in their judgments and more consistent. These results are thought to be explained in terms of the more highly developed organisation of the blind's tactile-kinaesthetic perception.     

The Impact of Criminal Record Stigma on Quality of Life: A Test of Theoretical Pathways

Across multiple stigmatized groups, research suggests that stigma may negatively impact individual wellbeing. This impact often occurs through a sequential pathway that includes perceiving societal stigma, a diminished and stereotyped self‐concept (i.e., internalized stigma), experiences of discrimination and rejection, and attempts to cope with stigma (e.g., secrecy or withdrawal). While prior research supports individual links within this pathway, no study has evaluated a model representing the relationships between all of these factors in relation to criminal record stigma. This study utilized cross‐sectional data from an online survey of 198 adults to test the pathways through which criminal record‐related stigma impacts individual quality of life. The results indicated that perceived stigma was a significant predictor of discrimination and rejection experiences, secrecy coping strategies, and decreased quality of life. There was also a significant indirect association between perceived stigma and quality of life through secrecy coping. Consistent with recent criminal record stigma research, internalized stigma was low among respondents. These findings point to the importance of reducing criminal record stigma and discrimination, so that individuals with criminal records have more opportunities to enhance their quality of life without having to withdraw from society or keep their record a secret.     

Discounting of food and water in rats shows trait- and state-like characteristics

Delay discounting is the loss in value of an outcome as a function of its delay. The present study focused on examining a trait-like characteristic of delay discounting in a preclinical animal model. Specifically, we were interested in whether there was a positive relation between discounting of 2 different outcomes in rats. That is, would rats that discount delayed food steeply also discount delayed water steeply? In addition, we examined how session-to-session variability in discounting could be attributed to differences between subjects (trait variability) and to differences within subjects (state variability). Finally, we measured discounting from early- to mid-adulthood, allowing us to examine changes in discounting as a function of age. Overall, we found a moderate, positive correlation between discounting of food and discounting of water in rats, providing further evidence that the relative consistency with which individuals discount different outcomes is a trait-like characteristic. In addition, we found a high degree of within-subject variability in discounting, indicating strong state-like differences from session to session. Finally, overall, discounting decreased as a function of age; however, individual-subject data showed variability in how discounting changed across time. Overall, our results show that differences in delay discounting between individuals reflect variability in both trait- and state-like characteristics.
