Color Vision in Alzheimer’s Patients: Can We Improve Object Recognition With Color Cues?

Sixty-three frail, elderly patients seen in a university-based outpatient geriatric assessment clinic were divided into three dementia diagnosis categories (Alzheimer’s disease, “other” dementias, cognitively intact) to investigate the use of color cues as memory aids. Recognition time was measured for three cues: (1) same color/different form; (2) same form/different color; and (3) different color/different form. Log transformed response times were longer for form cues (same color/different form) compared to color cues (different color/same form, p =.001; different color/different form, p <.001). No differences in log transformed response time were noted among dementia categories for each test condition. Color cues make a significant difference in short-term memory recall ability compared to form cues. Vivid color-coding the environment of a frail, elderly population may enhance short-term memory and improve functional ability. This may prove to be especially useful in long-term care settings, which provide services to a variety of people with differing cognitive abilities.     

The influence of gender‐stereotyped perfumes on leadership attribution

The classification of perfumes as ‘women's’ and ‘men's’ fragrances is based on certain gender stereotypes. In two experiments, female and male participants were asked to assume the role of a manager. In Experiment 1, they read an application for the position of a junior manager written by a male or female job applicant. Application papers were prepared with a typically masculine perfume, a typically feminine perfume or no perfume at all (control group). In Experiment 2, participants conducted a job interview with a female or male applicant (a confederate) who had applied the respective perfume or no perfume. Persons with a typically masculine perfume were ‘employed’ with a higher degree of certainty compared to persons with a typically feminine perfume. Copyright © 2002 John Wiley & Sons, Ltd.     

Valuing Environmental Outcomes: Preferences for Constant or Improving Sequences

Experimental results on individuals' preferences for temporal sequences of environmental outcomes related to air quality and near-shore ocean water quality are compared with preferences for sequences of health and monetary outcomes. Generally, graduate business student participants gave significantly lower ratings to environmental and health sequences (with equal means) that worsened over time, relative to the ratings they gave to sequences that either remained the same or improved over time. This pattern was reversed by the participants when they faced sequences of monetary payments. This preference structure held for both short (5-year) and long (50-year) time horizons, and it was confirmed with choice data. A model proposed by Loewenstein and Prelec for the valuation of sequences of outcomes was applied to the current data set and compared to the traditional discounting model. In all cases, the model that incorporated “Gestalt” features of the sequence (slope and uniformity) performed better than the net present value discounting model at predicting the mean ratings for the sequences in the different domains.     

Testimony work with Bosnian refugees: living in legal limbo

Mental health professionals working with refugees are often confronted with traumatised survivors who are living in legal limbo. Complicated asylum procedures or provisions of only 'temporary' protection trigger existential fears, reexperiencing of trauma and feelings of hopelessness and deep despair and can actively contribute to further destabilise survivors. Mental health centres have to reconceptualise their provided services for these clients. The paper introduces a testimony project for traumatised Bosnian refugees in Frankfurt, Germany, who were living in legal limbo for many years. The testimony method was used in combination with supportive therapy and informed advocacy to try to reduce the survivors' feelings of humiliation and demoralisation which for them were at the centre of their survival. By giving testimony, survivors benefited psychologically and became better able to cope with the difficult present. Feelings of self-worth and dignity could be regained and a trusting relationship between the survivor and the listener facilitated the therapeutic process. The testimony material documented human rights abuses both in the country of origin and in exile, helped us to perform informed advocacy for this group and informed a larger public on the psychological costs of refugee resettlement policies.     

Staring and Compliance: A Field Experiment on Hitchhiking

A field experiment was conducted in which a single male, a single female, or a male-female couple attempted to hitch rides at four different traffic locations, under conditions in which the hitchhikers either stared at or looked away from oncoming drivers. It was found that staring increased the probability of a driver stopping from .03 to .067 (z = 2.96, p = .003). The female was a more successful hitchhiker than either the male or the couple, (z = 2.215, p = .026; z = 1.861, p .063, respectively).     

Development of temporal patterning and vocal hesitations in spontaneous narratives

Narratives were told aloud by 12 boys and 12 girls at each of seven age levels in response to nine cartoon pictures. Speech rate increased with age, due to corresponding decreases in both legnth and frequency of unfilled pauses (UPs), although the two measures were themselves uncorrelated. Parenthetical remarks (PRs) increased with age, while repeats (Rs) decreased. Location of UPs (81% before function words) was stable over age levels. Comparisons with other experiments are made. Interrelationships of speaking and thinking are discussed in terms of the cognitive and linguistic functions of length and frequency of UPs, respectively. Theories that neglect multiple psychological determinants of speech behavior and/or concentrate on only one level or unit of encoding are rejected as inadequate.     

Task differences on conservation and transitivity problems

Task differences were assessed with 120 first graders in a 2 × 3 × 3 factorial design combining Socioeconomic level (middle vs lower), Concepts (conservation of length, transitivity of length, and conservation of continuous quantity), and Tasks (three tasks for each concept selected on the basis of frequency of usage). As predicted, task by concept interactions were found on all four task response measures. This finding is consistent with Piaget's concept of horizontal decalage and with Flavell and Wohlwill's competence-performance model, which proposes that intermediate phases of stage transition are characterized by considerable intertask differences and initial and final phases by intertask consistency in performance. The importance of investigating the effects of task variables on multiple dependent measures at various age levels and points in time was emphasized. Concept, task, and socioeconomic class differences were also found on some of the measures.     

Exteroceptive control of response under delayed reinforcement

Three white rats, after 50 continuous reinforcements, were exposed successively, under dim illumination, to reinforcement delays of 1, 3, 5, 7.5, 10, 15, and 20 sec, with prolonged training at the 20-sec level. Behavior was maintained at each level, and an increase in interval was accompanied by an increase in post-reinforcement pause. Subsequently, under both 20- and 30-sec delays, the animals were tested during half of each daily session to determine the effect of introducing darkness during each delay interval. The result of this stimulus “support” was to regularize and increase response rate for each animal at both interval values.
