Resurgence of time allocation

The resurgence of time allocation with pigeons was studied in three experiments. In Phase 1 of each experiment, response‐independent food occurred with different probabilities in the presence of two different keylights. Each peck on the key changed its color and the food probability in effect. In Phase 2, the food probabilities associated with each keylight were reversed and, in Phase 3, food was discontinued in the presence of either keylight. The food probabilities were .25 and .75, in Experiment 1, and 0.0 and 1.0 in Experiment 2. More time was allocated to the keylight correlated with more probable food in Phases 1 and 2, and in Phase 3 resurgence of time allocation occurred for two of three pigeons in Experiment 1, and for each of four pigeons in Experiment 2. Because time had to be allocated to either of the two alternatives in Experiments 1 and 2, however, it was difficult to characterize the time allocation patterns in Phase 3 as resurgence when changeover responding approached zero. In Experiment 3 this issue was addressed by providing a third alternative uncorrelated with food such that in each phase, after 30 s in the presence of either keylight correlated with food, the third alternative always was reinstated, requiring a response to access either of the two keylights correlated with food. In this experiment, the food probabilities were similar to those in Experiment 1. Resurgence of time allocation occurred for each of three pigeons under this procedure. The results of these experiments suggest that patterns of time allocation resurge similarly to discrete responses and to spatial and temporal patterns of responding.     

Extinction of likes and dislikes: effects of feature-specific attention allocation

The evaluative conditioning (EC) effect refers to the change in the liking of a neutral stimulus (conditioned stimulus, CS) due to its pairing with another stimulus (unconditioned stimulus, US). We examined whether the extinction rate of the EC effect is moderated by feature-specific attention allocation. In two experiments, CSs were abstract Gabor patches varying along two orthogonal, perceptual dimensions (i.e. spatial frequency and orientation). During the acquisition phase, one of these dimensions was predictive of the valence of the USs. During the extinction phase, CSs were presented alone and participants were asked to categorise the CSs either according to their valence, the perceptual dimension that was task-relevant during the acquisition phase, or a perceptual dimension that was task-irrelevant during the acquisition phase. As predicted, explicit valence measures revealed a linear increase in the extinction rate of the EC effect as participants were encouraged to assign attention to non-evaluative stimulus information during the extinction phase. In Experiment 1, Affect Misattribution Paradigm (AMP) data mimicked this pattern of results, although the effect just missed conventional levels of significance. In Experiment 2, the AMP data revealed an increase of the EC effect if attention was focused on evaluative stimulus information. Potential mechanisms to explain these findings are discussed.     

Salesperson ambidexterity and customer satisfaction: examining the role of customer demandingness,adaptive selling,and role conflict

This research investigates the effects of sales-service ambidexterity on salesperson role perceptions, behaviors, and customer satisfaction. Using a business-to-business, salesperson-customer sample, we build and test a model which highlights both the positive and negative consequences of this simultaneous goal pursuit. Specifically, while sales-service ambidexterity positively impacts adaptive selling behaviors, it also increases perceptions of role conflict among salespeople. Customer demandingness moderates these relationships. Taken together, the results provide insights for firms on how to manage their sales force to optimize both sales and service outcomes based on characteristics of their salespeople and customers.     

Identification of biological neurons using adaptive observers

Change detection performance is influenced by a number of factors, among which is the informativeness of targets. It has not been clarified, yet, whether the highly informative regions have a processing priority as a result of resource deployment from other tasks or whether it results from a better resource management. In this paper, we adopted a change detection paradigm in which thirty participants were randomly assigned to two groups: single (change detection task) and dual task [change detection and a simplified version of the Paced Auditory Serial Oppository Task (PASOT, Gow and Deary in J Clin Exp Neuropsychol 26:723–736, 2004), which implies a verbal effort]. Stimulus informativeness was defined as social relevance, that is, changing targets were people (high relevance) versus objects (low relevance), all other aspects (i.e., salience and position in the scene) kept constant. As hypothesized, data analyses showed a significant main effect of social relevance and task condition, i.e., better change detection performance and lower change detection times for people versus objects and for single than for dual task condition. Interestingly, the PASOT accuracy remained stable across the person versus object trials, thus implying that the better performance with socially relevant targets could not be explained by a resources withdrawal from the secondary task.

Impulsiveness and resource allocation: Testing Humphreys and Revelle’s (1984) explanation of impulsive personality

Humphreys and Revelle [Humphreys, M. S., Revelle, W. (1984). Personality, motivation and performance: A theory of the relationship between individual differences and information processing. Psychological Review, 91, 153–184] suggest that impulsive individuals have relatively greater capacity to improve performance through task-directed resource allocation. This implies that there will be a differential effect of increases in effort intensity on performance for high and low impulsive individuals. Two quasi-experiments tested this prediction using a relative-judgement task (total N = 108, 68 females), however neither revealed the predicted interaction. In light of these findings, we re-consider the Humphreys–Revelle model in relation to independent but potentially related theory and research.     

Interacting effects of worry and anxiety on attentional disengagement from threat

Recent work suggests that the ability to disengage attention from threatening information is impaired in people who suffer from anxiety and dysphoria. It has been suggested that this impaired ability to disengage from threat might specifically be associated with the tendency to perseverate about threat (i.e., worry), which is a main characteristic of anxiety disorders and a wide range of other psychopathologies. However, no studies have yet addressed this issue. The present study examined whether trait worry as well as worry intensity after experimental worry induction are associated with impaired ability to disengage attention from threatening cues (angry faces), independently from or in conjunction with anxiety. Sixty-one participants performed a visual cueing experiment that required detection of a target stimulus at one of two possible locations. Prior to the target neutral, happy or angry facial cues appeared at one of these two locations; when there is a relatively long period between the cue and the target (>300 ms), an overall faster responding to invalidly cued trials relative to validly cued trials is believed to indicate inhibition of return (IOR) to a recently attended location. A reduced IOR for angry faces was only found when both trait worry and anxiety were high. When anxiety was kept constant, both trait worry and state worry were associated with enhanced IOR for neutral faces instead. The results seem to suggest that specific threat-related deficiencies in IOR may be a function of the co-occurrence of worry and anxiety.     

The Relationship of Pregnancy Status to Job Satisfaction: An Exploratory Analysis

Forty-three women who had worked outside of the home prior to becoming pregnant and had returned to the same place of employment after the birth of their children participated in the study. To do so, they responded to a two-part questionnaire asking about their work lives (e.g., level of job satisfaction before, during, and after their pregnancies) and demographic characteristics (e.g., occupation). The results indicated that their job satisfaction was significantly greater before their pregnancies than either during or after their pregnancies. Job satisfaction during pregnancy had a significant, positive correlation with satisfaction with organizational maternity leave policies. Perceived reactions from women's coworkers and supervisors were also examined. Implications for these findings for organizations are discussed. Limitations of the study, and how they might be rectified in future research, are also addressed.     

The development of children's preferences for equality and equity across 13 individualistic and collectivist cultures

A concern for fairness is a fundamental and universal element of morality. To examine the extent to which cultural norms are integrated into fairness cognitions and influence social preferences regarding equality and equity, a large sample of children (N 2,163) aged 4–11 were tested in 13 diverse countries. Children participated in three versions of a third‐party, contextualized distributive justice game between two hypothetical recipients differing in terms of wealth, merit, and empathy. Social decision‐making in these games revealed universal age‐related shifts from equality‐based to equity‐based distribution motivations across cultures. However, differences in levels of individualism and collectivism between the 13 countries predicted the age and extent to which children favor equity in each condition. Children from the most individualistic cultures endorsed equitable distributions to a greater degree than children from more collectivist cultures when recipients differed in regards to wealth and merit. However, in an empathy context where recipients differed in injury, children from the most collectivist cultures exhibited greater preferences to distribute resource equitably compared to children from more individualistic cultures. Children from the more individualistic cultures also favored equitable distributions at an earlier age than children from more collectivist cultures overall. These results demonstrate aspects of both cross‐cultural similarity and divergence in the development of fairness preferences.     

难度－价值权衡情境下的项目选择及其眼动特征

本研究采用行为和眼动技术,通过设置难度—价值权衡情境,考察在学习时间有限的条件下,学习者如何选择学习项目,以及该过程如何发生。结果发现：(1)被试更多选择得分期望最高的项目,而非分值最高或最简单的项目。(2)选择学习项目的过程不存在计算项目得分期望的过程。结果表明,学习者项目选择不仅基于难度或价值,而是会权衡难度和价值,选择得分期望最高的项目。该过程不符合补偿性决策理论的预期,与非补偿性理论预期一致。     

儿童在不同卷入情境下基于资源价值的分配行为特点：内群体偏爱的作用

为探究不同卷入情境下儿童基于资源价值的分配行为特点以及内群体偏爱在其中的作用, 呈现给儿童两种实验情境：实验1, 134名5~8岁儿童在第一方情境下与来自内、外群体的一名儿童分配不同价值的物品, 结果发现7~8岁儿童公平分配比例与5~6岁儿童无显著差异; 实验2, 130名5~8岁儿童在第三方情境下给来自特定群体的两名儿童分配资源, 结果发现7~8岁儿童公平分配比例显著高于5~6岁儿童。两个实验均发现儿童的分配行为表现出内群体偏爱, 5~6岁儿童比7~8岁儿童更明显。并且, 5~6岁女生比男生有更明显的内群体偏爱, 但在7~8岁组无性别差异。此外, 只有7~8岁儿童的公平分配行为表现出卷入情境上的差异, 他们在第三方情境比第一方情境下更能做出公平分配, 但5~6岁儿童的公平分配行为并无情境差异。综上可见, 比起年幼儿童, 年长儿童基于资源价值的公平行为发展得更好, 并且在两种卷入情境下受内群体偏爱的影响均更小。
