In emotional research, efficient designs often rely on successful emotion induction. For visual stimulation, the only reliable
database available so far is the International Affective Picture System (IAPS). However, extensive use of these stimuli lowers
the impact of the images by increasing the knowledge that participants have of them. Moreover, the limited number of pictures
for specific themes in the IAPS database is a concern for studies centered on a specific emotion thematic and for designs
requiring a lot of trials from the same kind (e.g., EEG recordings). Thus, in the present article, we present a new database
of 730 pictures, the Geneva Affective PicturE Database, which was created to increase the availability of visual emotion stimuli.
Four specific negative contents were chosen: spiders, snakes, and scenes that induce emotions related to the violation of
moral and legal norms (human rights violation or animal mistreatment). Positive and neutral pictures were also included: Positive
pictures represent mainly human and animal babies as well as nature sceneries, whereas neutral pictures mainly depict inanimate
objects. The pictures were rated according to valence, arousal, and the congruence of the represented scene with internal
(moral) and external (legal) norms. The constitution of the database and the results of the picture ratings are presented. 相似文献

Multiple‐choice response formats are troublesome, as an item is often scored as solved simply because the examinee may be lucky at guessing the correct option. Instead of pertinent Item Response Theory models, which take guessing effects into account, this paper considers a psycho‐technological approach to re‐conceptualizing multiple‐choice response formats. The free‐response format is compared with two different multiple‐choice formats: a traditional format with a single correct response option and five distractors (‘1 of 6’), and another with five response options, three of them being distractors and two of them being correct (‘2 of 5’). For the latter format, an item is scored as mastered only if both correct response options and none of the distractors are marked. After the exclusion of a few items, the Rasch model analyses revealed appropriate fit for 188 items altogether. The resulting item‐difficulty parameters were used for comparison. The multiple‐choice format ‘1 of 6’ differs significantly from the multiple‐choice format ‘2 of 5’, while the latter does not differ significantly from the free‐response format. The lower difficulty of items ‘1 of 6’ suggests guessing effects. 相似文献

Suicides present a major complication during imprisonment and contribute essentially to the high mortality rate of prisoners. All international studies found increased suicide rates among prisoners in comparison to the general population. This article reviews general and individual risk factors for suicide in prison and possible contributing specific stress factors during imprisonment. The main results of the analysis of the European Annual Prison Statistics from 1997 to 2007 are presented referring to macrostructural determining risk factors for suicide in prison. Measurements and prevention strategies are briefly discussed. 相似文献

When do motor behaviors (mis)match affective stimuli? An evaluative coding view of approach and avoidance reactions 总被引:1,自引:0,他引:1
Affective-mapping effects between affective stimuli and lever movements are critically dependent upon the evaluative meaning of the response labels that are used in the task instructions. In Experiments 1 and 2, affective-mapping effects predicted by specific-muscle-activation and distance-regulation accounts were replicated when the standard response labels towards and away were used but were reversed when identical lever movements were labeled downwards and upwards. In Experiment 3, affective-mapping effects were produced with affectively labeled right and left lever movements that are intrinsically unrelated to approach and avoidance. Experiments 4 and 5 revealed that affective-mapping effects are not mediated by memory retrieval processes and depend on the execution of affectively coded responses. The results support the assumption that evaluative implications of action instructions assign affective codes to motor responses on a representational level that interact with stimulus evaluations on a response selection stage. 相似文献

In two causal learning experiments with human participants, the authors compared various associative theories that assumed either elemental (unique cue, modified unique cue, replaced elements model, and Harris' model) or configural processing of stimuli (Pearce's theory and a modification of it). The authors used modified patterning problems initially suggested by Redhead and Pearce (1995). Predictions for all theories were generated by computer simulations. Both configural theories and the unique cue approach failed to account for the observations. The replaced elements model was able to account for part of the data, but only if the replacement parameters could vary across discrimination problems. The Harris model and the modified unique cue approach, assuming that the salience of stimuli decreases with an increasing number of stimuli in a compound, successfully accounted for all of our data. This success implies that attentional factors should be explicitly taken into account in associative learning theory. 相似文献

How to say no: single- and dual-process theories of short-term recognition tested on negative probes
Three experiments with short-term recognition tasks are reported. In Experiments 1 and 2, participants decided whether a probe matched a list item specified by its spatial location. Items presented at study in a different location (intrusion probes) had to be rejected. Serial position curves of positive, new, and intrusion probes over the probed location's position were mostly parallel. Serial position curves of intrusion probes over their position of origin were again parallel to those of positive probes. Experiment 3 showed largely parallel serial position effects for positive probes and for intrusion probes plotted over positions in a relevant and an irrelevant list, respectively. The results support a dual-process theory in which recognition is based on familiarity and recollection, and recollection uses 2 retrieval routes, from context to item and from item to context. 相似文献

Effects of semantic processing of crowded characters were investigated using numbers as stimuli. In an identification task,
typical spacing effects in crowding were replicated. Using the same stimuli in a magnitude comparison task, a smaller effect
of spacing was observed as well as an effect of response congruency. These effects were replicated in a second experiment
with varying stimulus-onset asynchronies. In addition, decreasing performance with increasing onset-asynchrony (so-called
type-B masking) for incongruent flankers indicates semantic processing of target and flankers. The data show that semantic
processing takes place even in crowded stimuli. This argues strongly against common accounts of crowding in terms of early
stimulus-driven impairments of processing. 相似文献

This study examined the relationship between PMS and emotion-related electromyographic facial activity at different phases of the menstrual cycle. Twenty-four women of reproductive age (12 with PMS, 12 controls) participated in two EMG sessions (T1 and T2) in which they were shown photographic images that can elicit various emotions (IAPS stimuli). T1 took place in the follicular phase, T2 in the luteal phase. The activity of the musculus depressor anguli oris ("depressor", expression of sadness) was measured. Depressor activity was compared to activity of musculus orbicularis oculi ("orbicularis"; expression of joy). ANOVA yielded a significant increase of the activity of the depressor at T2 in the PMS group. The PMS group showed more frequent depressor activity during the luteal than the follicular phase. Orbicularis activity did not change from T1 to T2. Conclusions: The PMS group experienced various visual stimuli in a more depressed way during the luteal phase. 相似文献

Maladaptive social behavior is one of the defining characteristics of psychopathic personality disorder. Nevertheless, maladaptive social behavior has only rarely been observed among psychopaths in experimentally controlled situations. The authors assessed the behavior of criminal psychopaths from high-security psychiatric hospitals in a computer simulation of a social dilemma situation. The psychopaths showed a markedly higher proneness to competitive (i.e., noncooperative) behavior than did healthy adults from the general population. The odds ratio between defection and being a psychopath was estimated at 7.86 in the sample. The probability to choose selfish instead of cooperative behavior was significantly linked to the following subscales of the Psychopathy Personality Inventory-Revised (S. O. Lilienfeld & M. R. Widows, 2005): rebellious nonconformity, Machiavellian egocentricity, and the total score. On average, the psychopathic participants accumulated higher gain and more strongly exploited their counterpart than did the healthy participants. 相似文献
