Determinants of cumulative successive contrast in saltiness intensity judgments

When all stimuli elicit the same taste quality, solutions preceded by a high concentration level are judged to be significantly less intense than solutions preceded by a low concentration level. After repetitious stimulation with a different tasting stimulus, the intensity of the present stimulus is overestimated. This phenomenon is called “successive contrast.” In the present study, the cumulative effects of three identical stimuli on the saltiness ratings for a test stimulus are investigated. The preceding stimuli are manipulated with regard to taste quality, saltiness intensity, total taste intensity, and complexity. Whether the size of the cumulative contrast effect is associated with the degree of dissimilarity between preceding stimuli and test stimulus, or with the saltiness or total taste intensity of the preceding stimuli, is investigated. The size of the contrast effect depends on the type of preceding stimulus, its intensity, and the type of test stimulus. No association was found with judgments of the degree of dissimilarity between the preceding stimuli and the test stimulus. For nonsalty preceding stimuli, the contrast effects are independent of concentration level. When the preceding stimuli taste at least partly salty, the total intensity appears to determine the size of the contrast for an unmixed salty test stimulus.     

Women as cues for men's approach or distancing behavior: A study of interpersonal sexist discrimination

The purpose of this study was to investigate interpersonal sexist discrimination, operationally defined as distancing behavior. A heterogeneous sample of participants were approached at four train stations and completed two paper and pencil simulated seating measures, a sex role attitudes measure, and provided demographic information. It was predicted that in the neutral situations presented in the seating measures where there is a choice to sit either next to a man or a woman, men would more often choose to sit next to a man but women were not expected to make seating choices based on the gender of the person seated. Men's seating choices were found to be influenced by the gender of target persons whereas women's choices were not, but men either distanced from or approached women target persons. Self-reported sex role attitudes were found not to be related to distancing behavior.We gratefully acknowledge the assistance of Alyson Andrews, Nicholas Geraci, Scott Marino, Stacy Schiff, Robert Victoria, and Lisa Zamara, seniors at the University of Rhode Island, who served as investigators in this study and also assisted in the coding of data.

CHANGE IN AFTERIMAGE AND SPIRAL AFTEREFFECT SERIALS DUE TO ANXIETY CAUSED BY SUBLIMINAL THREAT

Experiments with projected negative afterimages and with the aftereffects of a rotating spiral were performed serially (repeated stimulus presentation). In the middle of the sequences the experimental groups were subjected to subliminal threat by means of a metacontrast technique. The effects of threat on the latter part of the sequences were according to predictions and differed markedly from the results in control groups.     

Correlates and consequences of uncertainty in career aspirations: Gender differences among adolescents in England

Young people today face a great deal of uncertainty regarding their career opportunities, yet relatively little information is known about the correlates and consequences of uncertain aspirations. Drawing upon the Longitudinal Study of Young People in England (LSYPE) born in 1989/90, this study examined a pathway model investigating whether uncertain career aspirations and other associated variables mediate the link between socioeconomic status and prior achievement and later educational outcomes. Gender differences were also examined. Findings indicate that adolescents who had lower prior achievement and were from lower socioeconomic backgrounds were more likely to have uncertainty in their career aspirations. The hypothesized model was supported to some extent, indicating that uncertain career aspirations and other associated variables were significant mediators. Unexpectedly, adolescents with uncertain career aspirations had higher academic performance at age 16 and a greater likelihood of educational enrollment at age 18 compared to those with high, certain aspirations, when parental educational expectations, school motivation, perceived academic ability and useful career advice were taken into account, suggesting that these young people may benefit from an extended period of moratorium in their career choice.     

Prior entry and temporal attention: cueing affects order errors in RSVP

The law of prior entry states that attended objects come to consciousness more quickly than unattended ones. This has been well established in spatial cueing paradigms, where two task-relevant stimuli are presented near-simultaneously at two different locations. Here, we suggest that prior entry also plays a pivotal role in temporal attention paradigms, where stimuli appear at the same location but at distinct moments in time, in rapid serial presentation (RSVP). Specifically, we hypothesize that prior entry can explain temporal order reversals in reporting two targets from RSVP. In support of this, three experiments show that cueing attention toward either of the targets has a strong influence on order errors. We conclude that prior entry provides a viable explanation of the way in which relevant information is prioritized in RSVP.     

Shifting attention among working memory representations: testing cue type, awareness, and strategic control

It is well known that visual working memory (VWM) performance is modulated by attentional cues presented during encoding. Interestingly, retrospective cues presented after encoding, but prior to the test phase also improve performance. This improvement in performance is termed the retro-cue benefit. We investigated whether the retro-cue benefit is sensitive to cue type, whether participants were aware of their improvement in performance due to the retro-cue, and whether the effect was under strategic control. Experiment 1 compared the potential cueing benefits of abrupt onset retro-cues relying on bottom-up attention, number retro-cues relying on top-down attention, and arrow retro-cues, relying on a mixture of both. We found a significant retro-cue effect only for arrow retro-cues. In Experiment 2, we tested participants' awareness of their use of the informative retro-cue and found that they were aware of their improved performance. In Experiment 3, we asked whether participants have strategic control over the retro-cue. The retro-cue was difficult to ignore, suggesting that strategic control is low. The retro-cue effect appears to be within conscious awareness but not under full strategic control.     

Spatial mislocalization as a consequence of sequential coding of stimuli

In three experiments, we tested whether sequentially coding two visual stimuli can create a spatial misperception of a visual moving stimulus. In Experiment 1, we showed that a spatial misperception, the flash-lag effect, is accompanied by a similar temporal misperception of first perceiving the flash and only then a change of the moving stimulus, when in fact the two events were exactly simultaneous. In Experiment 2, we demonstrated that when the spatial misperception of a flash-lag effect is absent, the temporal misperception is also absent. In Experiment 3, we extended these findings and showed that if the stimulus conditions require coding first a flash and subsequently a nearby moving stimulus, a spatial flash-lag effect is found, with the position of the moving stimulus being misperceived as shifted in the direction of its motion, whereas this spatial misperception is reversed so that the moving stimulus is misperceived as shifted in a direction opposite to its motion when the conditions require coding first the moving stimulus and then the flash. Together, the results demonstrate that sequential coding of two stimuli can lead to a spatial misperception whose direction can be predicted from the order of coding the moving object versus the flash. We propose an attentional sequential-coding explanation for the flash-lag effect and discuss its explanatory power with respect to related illusions (e.g., the Fr?hlich effect) and other explanations.     

Does own experience affect perception of others’ actions in capuchin monkeys (Cebus apella)?

Anticipating another’s actions is an important ability in social animals. Recent research suggests that in human adults and infants one’s own action experience facilitates understanding and anticipation of others’ actions. We investigated the link between first-person experience and perception of another’s action in adult tufted capuchin monkeys (Sapajus apella spp., formerly Cebus apella spp.). In Experiment 1, the monkeys observed a familiar human (actor) trying to open a container using either a familiar or an unfamiliar action. They looked for longer when the actor tried to open the container using a familiar action. In Experiment 2, the actor performed two novel actions on a new container. The monkeys looked equally at the two actions. In Experiment 3, the monkeys were trained to open the container using one of the novel actions in Experiment 2. After training, we repeated the same procedure as in Experiment 2. The monkeys looked for longer when the actor manipulated the container using the action they had practiced than when she used the unfamiliar action. These results show that knowledge derived from one’s own experience impacts perception of another’s action in these New World monkeys.     

“Heaven and Hell on Earth” A critical discourse analysis of religious terms in Norwegian autobiographies describing personal experience of mental health problems

This article explores the use of religious terms in six Norwegian autobiographies written between 1925 and 2005 by people who themselves have been patients in the mental health services. Through a critical discourse analysis, we discuss the functions of religious discourse in the texts and its position in contrast to the medical discourse predominant in today's mental health services. It was found that religious (predominantly Christian) terms were used to varying degrees in all autobiographies as a means to capture the immensity and inherent ambivalence characteristic of mental health problems. Despite the “medical turn” in professional mental health discourse, there is no clear evidence of a decrease in the use of religious terms from the oldest to the most recent text. We propose that professional mental health workers to a larger extent take into account the religious dimension in therapy, and reflect on its larger historical and sociocultural context.
