Trait anxiety and perceptual load as determinants of emotion processing in a fear conditioning paradigm

The impact of trait anxiety and perceptual load on selective attention was examined in a fear conditioning paradigm. A fear-conditioned angry face (CS+), an unconditioned angry face (CS-), or an unconditioned face with a neutral or happy expression were used in distractor interference and attentional probe tasks. In Experiments 1 and 2, participants classified centrally presented letters under two conditions of perceptual load. When perceptual load was high, distractors had no effect on selective attention, even with aversive conditioning. However, when perceptual load was low, strong response interference effects for CS+ face distractors were found for low trait-anxious participants. Across both experiments, this enhanced distractor interference reversed to strong facilitation effects for those reporting high trait anxiety. Thus, high trait-anxious participants were faster, rather than slower, when ignoring CS+ distractors. Using an attentional probe task in Experiment 3, it was found that fear conditioning resulted in strong attentional avoidance in a high trait-anxious group, which contrasted with enhanced vigilance in a low trait-anxious group. These results demonstrate that the impact of fear conditioning on attention is modulated by individual variation in trait anxiety when perceptual load is low. Fear conditioning elicits an avoidance of threat-relevant stimuli in high trait-anxious participants.     

Potentiation and overshadowing of shape by wall color in a kite-shaped maze using rats in a foraging task

The interaction between redundant geometric and featural cues in open field search tasks has been examined widely with results that are not always consistent. Cheng (1986) found evidence that when searching for food in rectangular environments, rats used the geometrical characteristics of the environment rather than local featural cues, suggesting that geometry had overshadowed featural cues. More recently, Graham et al. (2006) and Pearce et al. (2006) found that wall color facilitated (potentiated) learning about the shape of the environment by rats in a kite-shaped water maze. The first experiment in the present research replicated the paradigm used by Graham et al. and Pearce et al. using rats in a foraging situation, but with conditions similar, and found the same results, potentiation of shape by color. Experiments 2 and 3 revealed overshadowing instead of potentiation of shape by wall color under the same conditions except that the wall colors of the test environment were not the same as those used during training. The results are consistent with an analysis of the role of associations formed between wall color and geometry in such situations (Rhodes et al., 2009) and extend our understanding of how featural and spatial cues interact.     

A test of the tau-dot hypothesis of braking control in the real world

A controlled experiment used instrumented vehicles in a real-world driving task to compare D. N. Lee's (1976) tau-dot hypothesis of braking control with an alternative based on the direct estimation and control of ideal deceleration (T. Yates, M. Harris, & P. Rock, 2004). Drivers braked to stop as closely as possible to a visual target from different starting speeds and times-to-contact. The data provided little support for the tau-dot hypothesis, and analysis suggested that braking in the real world is better explained by a direct deceleration strategy.     

Intuitive Covariation Assessment of the Illusory Correlation

Most of the research concerned with the illusory correlation is modeled after the seminal work of D. L. Hamilton and R. K. Gifford (1976). However, S. A. Haslam and C. McGarty (1994) have voiced concerns over the dependent measures used within this paradigm. Therefore, in this study, the authors tested a new dependent variable that has high face validity. This measure was modeled after the work of J. R. McGahan and R. Wight (1989) and consisted of a set of propositional statements representing either the illusory correlation, the contingency opposite the illusory correlation, or the noncontingency. A second purpose of this study was to validate other studies that have used dependent measures modeled after the work of J. R. McGahan and R. Wight (1989). Demonstrating that this measure can be used to detect a well-documented phenomenon (i.e., the illusory correlation) would strengthen the results and conclusions from other studies. To this end, results from 2 experiments indicate that this measure does provide a valid alternative to those measures that are commonly used in illusory correlation studies. The results thereby give credence to other studies that have used similar dependent measures.     

Gender Bias on the Thematic Apperception Test

Thirty male and 30 female college students generated stories to a set of nine Thematic Apperception Test (TAT) cards with either male or female stimulus characters. The Fine scoring system was factor analyzed to produce seven factor clusters plus three outcome variables. Multiple analysis of variance (MANOVA) revealed a main effect for type of card. The female TAT cards elicited significantly more responses on the General Concerns scale than did the male TAT cards. A main effect for subject gender showed the females gave more responses than males on the Interpersonal Relations scale. No differences were found on the outcome variables.     

Parental experience of childhood cancer using Interpretative Phenomenological Analysis

Whilst survival rates for childhood cancer have improved dramatically over the past three decades, it is still a devastating diagnosis for family members and an illness which severely disrupts the lifestyle of the family unit. Developing an understanding of the impact of the illness on the family is crucial to better support families’ deal with the demands of the illness. In this study nine families in which a child was diagnosed with cancer were interviewed twice over a 12 month period, approximately 6 months apart. Using Interpretative Phenomenological Analysis, a semi-structured interview was used to explicate parent's experience of childhood cancer. The results revealed five super-ordinate themes; (1) a pivotal moment in time, (2) the experience of adaptation in relation to having a sick child, (3) the nature of support, (4) re-evaluation of values during a critical life experience and (5) the experience of optimism and altruism. Findings indicate that parents express both negative and positive experiences as they re-evaluate the meaning and purpose of life, seek to redefine themselves, often in terms of priorities, relationships, sense of community and achieve degrees of optimism and altruism. Implications for addressing the needs of parents and for further research are discussed.     

Influence of televised modeling and verbalization on children's delay of gratification

Voluntary delay of gratification in 9-year-old children was assessed 4 weeks prior to, immediately after, and 4 weeks subsequent to exposure to one of four televized films. The modeling group observed an adult female model exemplify high-delay behavior. The persuasion group observed the model verbalize good reasons for waiting. The persuasion-modeling group observed the model exemplify high-delay behavior and verbalize reasons for waiting. Subjects in each of the treatment groups emitted more delay choices on the posttest than control group subjects who observed the model exhibit neutral behavior. The greatest magnitude of change occurred when modeling and persuasive cues were combined. Treatment effects were still in evidence for the modeling and the persuasion-modeling groups after a period of 4 weeks.     

Good looks and good practice: the attitudes of career practitioners to attractiveness and appearance

Empirical evidence attests the impact that career image has on objective career success, yet little is known of how career practitioners conceptualise and operationalise this information. This article presents the quantitative findings of an online survey of career practitioners (n?=?399, 74% female, 89% white and 75% from the U.K.) exploring their attitudes and practices towards issues of appearance and attractiveness. Career practitioners who participated in this survey acknowledged that beauty, self-presentation and interpersonal skills influence career success, and 96% of them considered conversations about career image as part of their professional remit. The career practitioners felt relatively comfortable and well informed in their discussions in this arena, but would welcome further guidance and training to inform their practice. Ethical and practical implications for the profession are considered.
