语言差异对跨通道情绪启动效应的影响

采用跨通道启动范式,探讨言语与面孔情绪加工的相互影响效应,以及语言差异（母语：汉语;非母语：英语）在其中的影响作用。实验1以言语情绪词为启动刺激,面孔情绪为目标刺激,结果发现,相比于英语启动刺激条件,在汉语启动刺激条件下的面孔情绪判断具有更好的表现;在积极情绪启动条件下,言语情绪刺激能够启动面孔情绪刺激。实验2以面孔情绪为启动刺激,言语情绪词为目标刺激,结果发现,相比于英语目标刺激条件,在汉语目标刺激条件下的言语情绪判断具有更好的表现;在积极情绪启动条件下,面孔情绪刺激能够启动言语情绪刺激。研究结果表明,言语情绪与面孔情绪的加工能够相互影响,但这种相互关系仅表现在积极情绪启动条件下。此外,母语和非母语在情绪功能上具有差异性。     

Representation of memory for order of mental operations in cognitive tasks

Recent research shows that people learning a cognitive task acquire a memory for the order of operations applied, independent of the data to which those operations were applied. We designed two experiments to show how this sequence memory is represented. Experiment 1 compared predictions based on 3 possible sequence representation methods: composition, dyad transition, and associative chain. Latency and error results from a simple sequential task supported the associative chain representation. The associative links between operations presumably enhance performance by priming subsequent operations but do not operate in an all-or-none fashion. Experiment 2 explored whether transfer items that matched the first 2 rules and first 3 elements of a training item could bias participants toward executing a composed production learned during training. Latency and undetected error results were consistent with an associative chain representation but not with additional predictions made by the composition representation. These two experiments support the representation of operation sequences in memory as an associative chain.     

GROUP FORAGING SENSITIVITY TO PREDICTABLE AND UNPREDICTABLE CHANGES IN FOOD DISTRIBUTION: PAST EXPERIENCE OR PRESENT CIRCUMSTANCES?

The ideal free distribution theory (Fretwell & Lucas, 1970) predicts that the ratio of foragers at two patches will equal the ratio of food resources obtained at the two patches. The theory assumes that foragers have "perfect knowledge" of patch profitability and that patch choice maximizes fitness. How foragers assess patch profitability has been debated extensively. One assessment strategy may be the use of past experience with a patch. Under stable environmental conditions, this strategy enhances fitness. However, in a highly unpredictable environment, past experience may provide inaccurate information about current conditions. Thus, in a nonstable environment, a strategy that allows rapid adjustment to present circumstances may be more beneficial. Evidence for this type of strategy has been found in individual choice. In the present experiments, a flock of pigeons foraged at two patches for food items and demonstrated results similar to those found in individual choice. Experiment 1 utilized predictable and unpredictable sequences of resource ratios presented across days or within a single session. Current foraging decisions depended on past experience, but that dependence diminished when the current foraging environment became more unpredictable. Experiment 2 repeated Experiment I with a different flock of pigeons under more controlled circumstances in an indoor coop and produced similar results.     

Preference and resistance to change in concurrent variable-interval schedules

Pigeons were trained on a multiple schedule in which separate concurrent schedules were presented in the two components of the schedule. During one component, concurrent variable-interval 40-sec variable-interval 80-sec schedules operated. In the second component, concurrent variable-interval 40-sec variable-interval 20-sec schedules operated. After stable baseline performance was obtained in both components, extinction probe choice tests were presented to assess preference between the variable-interval 40-sec schedules from the two components. The variable-interval 40-sec schedule paired with the variable-interval 80-sec schedule was preferred over the variable-interval 40-sec schedule paired with the variable-interval 20-sec schedule. The subjects were also exposed to several resistance-to-change manipulations: (1) prefeeding prior to the experimental session, (2) a free-food schedule added to timeout periods separating components, and (3) extinction. The results indicated that preference and resistance to change do not necessarily covary.     

Sets and Classes as Many

In this paper the view is developed that classes should not be understood as individuals, but, rather, as classes as many of individuals. To correlate classes with individuals labelling and colabelling functions are introduced and sets identified with a certain subdomain of the classes on which the labelling and colabelling functions are mutually inverse. A minimal axiomatization of the resulting system is formulated and some of its extensions are related to various systems of set theory, including nonwellfounded set theories.     

初中生认同的亲社会行为的初步研究

通过对8名11～14岁初中生的深入访谈,初步探讨了处于初中阶段的青少年认同的亲社会行为。发现:(1)初中生最认同的亲社会行为是帮助行为,其次是交往行为。此外,安慰行为、公益行为、礼貌行为和遵规行为也被他们认同;(2)初中生对不同行为主体间发生的亲社会行为的认同有明显差异,他们更关心发生在他们之间的亲社会行为;(3)普通学校、打工子弟学校的初中生对帮助行为和交往行为认同的比率差异明显;(4)初中生认同的亲社会行为的种类不存在明显的性别差异。     

Sensory discrimination and intelligence: testing Spearman's other hypothesis

At the centenary of Spearman's seminal 1904 article, his general intelligence hypothesis remains one of the most influential in psychology. Less well known is the article's other hypothesis that there is "a correspondence between what may provisionally be called 'General Discrimination' and 'General Intelligence' which works out with great approximation to one or absoluteness" (Spearman, 1904, p. 284). Studies that do not find high correlations between psychometric intelligence and single sensory discrimination tests do not falsify this hypothesis. This study is the first directly to address Spearman's general intelligence-general sensory discrimination hypothesis. It attempts to replicate his findings with a similar sample of schoolchildren. In a well-fitting structural equation model of the data, general intelligence and general discrimination correlated .92. In a reanalysis of data published byActon and Schroeder (2001), general intelligence and general sensory ability correlated .68 in men and women. One hundred years after its conception, Spearman's other hypothesis achieves some confirmation. The association between general intelligence and general sensory ability remains to be replicated and explained.     

Concurrent validity of the Peabody Picture Vocabulary Test-Third Edition as an intelligence and achievement screener for low SES African American children

Authors tested the validity of the Peabody Picture Vocabulary Test-Third Edition (PPVT-III) as a screening measure for intelligence and achievement. The PPVT-III and Kaufman Assessment Battery for Children (KABC) were administered to 416 African American children of low socioeconomic status in a counterbalanced design. Results indicated that the PPVT-III correlated .58 with the KABC Mental Processing Composite (MPC) score; however, participants scored significantly lower (M = 8.3 points) on the PPVT-III than on the MPC. Although receiver operating characteristic (ROC) analyses supported the use of the PPVT-III as a valid intellectual and achievement screener, the selection of a single cutoff score for the PPVT-III was problematic. The purpose of the screening program should guide selection of a cutoff score for the PPVT-III.     

Semantic priming in Alzheimer's dementia: evidence for dissociation of automatic and attentional processes

The nature of the semantic memory deficit in dementia of the Alzheimer's type (DAT) was investigated in a semantic priming task which was designed to assess both automatic and attention-induced priming effects. Ten DAT patients and 10 age-matched control subjects completed a word naming semantic priming task in which both relatedness proportion (RP) and stimulus-onset asynchrony (SOA) were varied. A clear dissociation between automatic and attentional priming effects in both groups was demonstrated; however, the DAT subjects' pattern of priming deviated significantly from that of the normal controls. The DAT patients failed to produce any priming under conditions which encouraged automatic semantic processing and produced facilitation only when the RP was high. In addition, the DAT group produced hyperpriming, with significantly larger facilitation effects than the control group. These results suggest an impairment of automatic spreading activation in DAT and have implications for theories of semantic memory impairment in DAT as well as models of normal priming.     

Conducting industrial and organizational psychological research: institutional review of research in work organizations

Although informed consent is a primary mechanism for ensuring the ethical treatment of human participants in research, both federal guidelines and American Psychological Association ethical standards recognize that exceptions to it are reasonable under certain conditions. However, agreement about what constitutes a reasonable exception to informed consent is sometimes lacking. We presented the same protocols to samples of respondents drawn from 4 populations: Institutional review board (IRB) members, managers, employees, and university faculty who were not members of IRBs. Differences in perceptions of IRB members from the other samples with respect to the risks of the protocols without informed consent and on the feasibility of conducting the research in employment organizations are discussed in terms of implications for industrial and organizational psychology research.
