The Significance of the Fluctuations Experienced in Observing Ambiguous Figures and in Binocular Rivalry

This study investigated predictions from Mednick's remote associates theory as to unusualness of response in a word association task as a function of remote associational ability (high or low scores on the RAT), the nature of the verbal stimulus (flat or steep hierarchy words), and the serial position of the response. Ss were Ohio high school students. Although high RAT scorers gave significantly less unusual responses overall than did low RAT scorers, results were interpreted as generally supportive of the theory. Low RAT scorers moved more rapidly to less frequent responses than did high RAT scorers, later responses were more infrequent than earlier responses in the sample tested, and while word-type did not in itself determine unusualness of response, it did interact with the other variables in a manner consistent with the theory.     

Alternate Forms of the Matching Familiar Figures Test: A Critical Note

Criticism is leveled at attempts to develop alternative forms of the Matching Familiar Figures test when the literature suggests that what is required is a more reliable test, not simply an alternate version.     

Variable Perception of White Noise in Ambiguous Phonetic Contexts: The Case of /p/ and /f/

The roles of spectro-temporal coherence, lexical status, and word position in the perception of speech in acoustic signals containing a mixture of speech and nonspeech sounds were investigated. Stimuli consisted of nine (non)words in which either white noise was inserted only into the silent interval preceding and/or following the onset of vocalic transitions ambiguous between /p/ and /f/, or in which white noise overlaid the entire utterance. Ten listeners perceived 85% /f/s when noise was inserted only into the silent interval signaling a stop closure, 47% /f/s when noise overlaid the entire (non)words, and 1% in the control condition that contained no noise. Effects of spectro-temporal coherence seemed to have dominated perceptual outcomes, although the lexical status and position of the critical phoneme also appeared to affect responses. The results are explained more adequately by the theory of Auditory Scene Analysis than by the Motor Theory of Speech Perception.     

Blushing May Signify Guilt: Revealing Effects of Blushing in Ambiguous Social Situations

Although blushing after a social infraction can function as a remedial gesture, people generally consider blushing as an undesirable response. To address this apparent inconsistency, we tested the idea that blushing has remedial properties after clear-cut antecedent behaviors, but can undermine the actor's image in ambiguous situations. In Experiment 1, participants (N = 49) read vignettes referring to prototypical mishaps, transgressions, and ambiguous situations. In Experiment 2 (N = 58), we specifically varied the actor's intentionality while keeping the actor's behavior constant. In support of its alleged face-saving properties, blushing had remedial effects after obvious mishaps and voluntary transgressions. However, in ambiguous social situations and after transgressions that are ambiguous with respect to the actor's intentionality, blushing undermined the actor's trustworthiness.     

Valence and Origin of Emotional Words Influence on Subsequent Perception of Ambiguous Stimuli in Terms of Competence Versus Warmth

The aim of this study was to examine whether the valence and origin of emotional words can alter perception of ambiguous objects in terms of warmth versus competence, fundamental dimensions of social cognition. 60 individuals were invited into the study focusing on the limits of intuition. They were asked to try to guess the meaning of Japanese pictorial signs in terms of their warmth versus competence connotations. Before each trial a subsequent memory load task was applied. Participants were supposed to read and remember words creating a factorial manipulation of valence (three levels) and origins (three levels: automatic, neutral and reflective) of affective connotations presenting to them for 500 ms. For positively valenced words, automatic originated ones resulted in perception of ambiguous signs more in terms of warmth, while reflective originated words resulted in perception of signs more in terms of competence. This study shows that social perception of warmth versus competence is susceptible to emotional influence of unrelated stimulation, and thus can be primed by objects in the environment. Warmth may be treated as linked with automatic mind processes, while competence may be treated as associated with the controlled part of the mind. In a broader context, this experiment results support claim that distinct dualities identified in dual-processes theories of mind are related to one another, and in fact they may be emanations of two more general systems of mind.     

Reactions to Patients who Complain of Pain: Effects of Ambiguous Diagnosis1

Reactions to patients who complain of pain were explored in an experimental study in which nursing students viewed a videotape of a “hospital patient”. The medical diagnosis and the physical attractiveness of the patient were systematically varied. Results indicated that an ambiguous diagnosis itself led to a negative impression of the patient, rather than leading to the use of nonrnedically relevant information (physical attractiveness) to form an impression. Patients with an ambiguous diagnosis were rated less favorably on trait adjectives, and their pain was seen as less genuine.     

Male Body Depilation: Prevalence and Associated Features of Body Hair Removal

In order to investigate the relatively new phenomenon of male body depilation, 118 male university students provided details regarding the reduction and removal of their body hair using a questionnaire developed from the results of structured interviews (Boroughs & Thompson, 2002). It was found that well over one-half of the sample (63.6%) was engaged in body depilation (i.e., the reduction or removal of body hair below the neck). The sites, methods, reasons, and injuries related to body depilation were assessed, as well as its effect on affective dimensions. Findings are considered in light of these ramifications and how they may contribute to a better understanding of men’s body image.     

Processing of Ambiguous Facial Affect in Adolescents with Depressive Symptoms Prior to and Following Social Exclusion: The Role of Perceptual Sensitivity and Response Bias

Depressive symptoms in adolescents are an important mental health issue and are associated with adverse developmental outcomes. Impairments in facial affect processing are considered an important factor in the etiology of depression. However, studies on facial affect processing in youth with depressive symptoms are lacking. This study investigated alterations in facial affect processing and the underlying mechanisms (perceptual sensitivity vs. response bias) related to adolescent depression, as well as the potential impact of negative social experiences. Sixty adolescents (M age?=?13.24, SD?=?1.03, 66.7 % female) with high (HD) and low (LD) depressive symptoms rated the predominant affective expression in ambiguous stimuli with varying intensity (happy-sad, happy-angry, sad-angry) prior to and following a negative (social rejection), positive (social inclusion), or no social experience with the depicted model identities. There were no baseline differences between groups. The LD group exhibited an increased perceptual sensitivity to happy expressions depicted by benevolent and stranger models, whereas the HD exhibited a higher sensitivity toward happy expressions depicted by rejecting social partners. The results suggest that depressive symptoms in adolescents may be associated with an altered processing of facial affect for partners who had previously rejected them. Implications of these findings for development and maintenance of adolescent depression are discussed.     

Workplace Helping: Interactive Effects of Personality and Momentary Positive Affect

We investigated interactions between positive affect and personality (empathy and altruism) as predictors of workplace helping. We conducted an experience sampling study with 80 participants, each of whom completed personality instruments and responded to a maximum of 5 electronic surveys per day for 5 workdays. This approach allowed us to study relationships over time between momentary positive affect and workplace helping behavior. We found that affect's relationship with later helping depended on the personality trait of altruism. We also found evidence that the relationship was reciprocal—helping others lead to increased positive affect, but again the relationship depended on altruism.     

Predicting the Effects of Actions: Interactions of Perception and Action

Many theories in cognitive psychology assume that perception and action systems are clearly separated from the cognitive system. Other theories suggest that important cognitive functions reside in the interactions between these systems. One consequence of the latter claim is that the action system may contribute to predicting the future consequences of currently perceived actions. In particular, such predictions might be more accurate when one observes one's own actions than when one observes another person's actions, because in the former case the system that plans the action is the same system that contributes to predicting the action's effects. In the present study, participants (N = watched video clips displaying either themselves or somebody else throwing a dart at a target board and predicted the dart's landing position. The predictions were more accurate when participants watched themselves acting. This result provides evidence for the claim that perceptual input can be linked with the action system to predict future outcomes of actions.     

Effects of Photographs in News-Magazine Reports on issue Perception

The influence of photographs in news-magazine reports was investigated in two related studies. One report addressed the economics of farming and focused on the growing gap between poor and rich farmers. The other report examined safety at amusement parks. The reports featured either no photograph, a photograph exemplifying one side of the issue (poor farmers, safe fun at parks), the opposite side of the issue (rich farmers, accidents at parks), or two photographs exemplifying both sides of the issue (poor and rich farmers, safe fun and accidents at parks). Issue perception was ascertained immediately or 10 days after exposure. Perception of farming economics was strongly influenced by the one-sided use of photographs. In the delay condition especially, assessments were biased in the direction suggested by the photographs. The perception of park safety was similarly influenced, but only by the danger-projecting photograph. The findings urge the balanced use of photographs for multifaceted issue reports.     

Group Size Effects on Risk Perception: A Test of Several Hypotheses

Yamaguchi (1998) found that people perceived a lower level of risk in a group than when they were alone, despite the fact that being in a group did not reduce the objective level of risk. Three experiments were conducted to examine several potential explanations for this effect. Experiment 1 replicated the group size effect in self-perception as well as the perception of the risk level of others. Results did not support the interdependence hypothesis and the affiliation hypothesis. Experiments 2 and 3 tested a hypothesis based on the availability heuristic. The group size effect was reduced or nullified when the target of risk judgment was associated with risk-seeking behavior or when an accident, in which many people died, was made salient.     

Neurocognitive Effects of Methamphetamine: A Critical Review and Meta-analysis

This review provides a critical analysis of the central nervous system effects of acute and chronic methamphetamine (MA) use, which is linked to numerous adverse psychosocial, neuropsychiatric, and medical problems. A meta-analysis of the neuropsychological effects of MA abuse/dependence revealed broadly medium effect sizes, showing deficits in episodic memory, executive functions, information processing speed, motor skills, language, and visuoconstructional abilities. The neuropsychological deficits associated with MA abuse/dependence are interpreted with regard to their possible neural mechanisms, most notably MA-associated frontostriatal neurotoxicity. In addition, potential explanatory factors are considered, including demographics (e.g., gender), MA use characteristics (e.g., duration of abstinence), and the influence of common psychiatric (e.g., other substance-related disorders) and neuromedical (e.g., HIV infection) comorbidities. Finally, these findings are discussed with respect to their potential contribution to the clinical management of persons with MA abuse/dependence.     

Sexual Harassment in the Workplace: Exploring the Effects of Attractiveness on Perception of Harassment

This study was designed to explore the effect of attractiveness on perceptions of sexual harassment. Male and female college students (N = 150) rated four scenarios depicting ambiguous incidents of sexual harassment, each paired with photos of a male boss and a female secretary. Male and female attractiveness was varied in a 2 × 2 factorial design. Participants were asked to rate each photo on a series of traits before making harassment judgments. Overall, females perceived more harassment. The behavior of attractive males was less likely to be seen as harassing. Attractive females were more likely to be seen as harassed, especially when the potential harasser was unattractive. The possible mechanisms underlying the effects of attractiveness were explored with the results supporting a direct effect of stereotypes over a mediating role for implicit personality theories.     

Perception of movement in American Sign Language: Effects of linguistic structure and linguistic experience

In order to reveal the psychological representation of movement from American Sign Language (ASL), deaf native signers and hearing subjects unfamiliar with sign were asked to make triadic comparisons of movements that had been isolated from lexical and from grammatically inflected signs. An analysis of the similarity judgments revealed a small set of physically specifiable dimensions that accounted for most of the variance. The dimensions underlying the perception of lexical movement were in general different from those underlying inflectional movement, for both groups of subjects. Most strikingly, deaf and hearing subjects significantly differed in their patterns of dimensional salience for movements, both at the lexical and at the inflectional levels. Linguistically relevant dimensions were of increased salience to native signers. The difference in perception of linguistic movement by native signers and by naive observers demonstrates that modification of natural perceptual categories after language acquisition is not bound to a particular transmission modality, but rather can be a more general consequence of acquiring a formal linguistic system.     

Party Pooper or Life of the Party: Dampening and Enhancing of Positive Affect in a Peer Context

Dampening and enhancing responses to positive affect have been linked to depressive symptoms. The main aim of the present study was to examine such responses in an interpersonal peer context and to examine their relation with depressive symptoms. A community sample of 665 seventh-graders (52.0% girls, Mage = 12.7 years) took part in the study. Using a newly developed questionnaire, the Co-Dampening and Co-Enhancing Questionnaire (CoDEQ), a two-factor model distinguishing co-dampening and co-enhancing was validated. Relations with general depressive symptoms, anhedonic symptoms, and friendship quality were investigated. The direction of relations was examined over a 1-year interval using cross-lagged analyses. Cross-sectional results revealed that higher levels of co-dampening and lower levels of co-enhancing were associated with more depressive and anhedonic symptoms, while controlling for co-rumination levels. For anhedonic symptoms, this pattern also held over and above intrapersonal dampening and enhancing. Friendship quality was related to higher concurrent levels of co-enhancing and lower levels of co-dampening. The longitudinal results pointed towards a scar model, in that both depressive and anhedonic symptoms predicted relative increases in co-dampening over time; however, this did not hold in a model in which dampening and enhancing were included as control variables.
