Why do some dieters succeed in controlling their diet while others do not? This research focused on a perceptual process—size perception of food objects—that may moderate the success of dieters in self-control dilemmas. We assessed successful and unsuccessful dieters' size perception of palatable food (Study 1) and diet-food (Study 2) after pre-exposing them to tempting food primes. Dieters perceived palatable food as bigger when primed with tempting food (vs. control prime), regardless of self-regulatory success in dieting (Study 1). Palatable food thus looms larger for both unsuccessful and successful dieters when in a “hot” state. In contrast, the perceived size of diet-food was increased by a tempting food prime only for successful dieters, but decreased for unsuccessful dieters (Study 2). These results are interpreted in terms of differences in the mental accessibility of competing goals (eating enjoyment vs. dieting) in successful vs. unsuccessful dieters. Indeed, when the dieting goal was made accessible for all dieters by a diet prime, even unsuccessful dieters perceived diet-food as bigger (Study 2). This research provides insight into a perceptual process that may be detrimental or beneficial in resolving self-control conflicts in the domain of eating and dieting behavior—and probably other domains of self-control as well. 相似文献

In two experiments, we investigated time perception during apparent biological motion. Pictures of initial, intermediate, and final positions of a single movement were presented, with interstimulus intervals that were constant within trials but varied across trials. Movement paths were manipulated by changing the sequential order of body postures. Increasing the path length produced an increase in perceived movement velocity. To produce an implicit measure of apparent movement dynamics, we also asked participants to judge the duration of a frame surrounding the stimuli. Longer paths with higher apparent movement velocity produced shorter perceived durations. This temporal bias was attenuated for nonbody (Experiment 1) and inverted-body (Experiment 2) control stimuli. As an explanation for these findings, we propose an automatic top-down mechanism of biological-motion perception that binds successive body postures into a continuous perception of movement. We show that this mechanism is associated with velocity-dependent temporal compression. Furthermore, this mechanism operates on-line, bridging the intervals between static stimuli, and is specific to configural processing of body form. 相似文献

Many theories argue that goal striving is more intense when people have optimistic expectancies for achieving the goal and
when attention is self-focused. Brehm’s motivational intensity theory, however, predicts that the intensity of motivation
is only as high as necessary, so people will try harder for difficult tasks than for easy tasks, all else equal. The present
experiment compared these two approaches by manipulating two levels of self-focused attention (low and high self-awareness,
via a mirror) and two levels of task difficulty (easy and difficult). Effort was assessed as cardiovascular reactivity, particularly
change in systolic blood pressure. Neither high self-focus nor an easy task per se caused increased effort; instead, high
self-focus significantly increased systolic reactivity when the task was difficult. Effort was thus higher despite less optimistic
goal expectancies, a finding that is predicted by Brehm’s motivational intensity theory but not by traditional self-regulation
models. 相似文献

Why do chronic dieters often violate their dieting goals? One possibility is that they experience stronger hedonic responses to tempting food than normal eaters do. We scrutinized hedonic processing in dieters and normal eaters (a) by manipulating food preexposure and (b) by assessing both immediate and delayed hedonic responses to tempting food with an adapted affect-misattribution procedure. Without food preexposure, dieters showed less positive hedonic responses than normal eaters (Study 1). When preexposed to tempting-food stimuli, however, dieters exhibited more positive delayed hedonic responses than normal eaters (Studies 1 and 2). Furthermore, delayed hedonic responding was meaningfully related to self-reported power of food and state cravings (Study 2). These findings suggest that dieters experience difficulties in down-regulating hedonic affect when in a "hot" state and that self-regulation research may benefit from a greater emphasis on temporal dynamics rather than static differences. 相似文献

Earlier findings have shown that positive evaluations about oneself, life, and future are related to each other and can be traced to a common latent dimension originally named positive orientation and then positivity. Further findings have led to the development of an eight‐item scale that allows a direct measurement of positivity. A review is presented of the major findings that point to positivity as a basic self‐evaluative disposition and that attest to its relevant impact across domains of functioning. Finally, possible avenues for promoting positivity and to allow individuals to fully benefit from it are discussed. 相似文献

Social information processing has been found to vary as a function of whether perceivers categorize individuals in terms of self and other (SO‐categorization) or using categories associated with the third pronominal person (3P‐categorization). Normal children aged 3–8, autistic children aged 5–9 and adult students were presented with decision tasks that enabled us to assess the use of SO‐ and 3P‐categorizations. A breakthrough of the SO‐categorization was observed at age 5. The hypothesis that 3P‐categorization precedes SO‐categorization was strongly disconfirmed, only adults showing consistent 3P‐categorization. Although previous research suggested a strong association between SO‐categorization and ‘I–Thou’ related social understanding, performances of autistic children suggested that impaired understanding of mental life does not detract from the ability to use SO‐categorization. 相似文献

This research examines decisions from experience in restless bandit problems. Two experiments revealed four main effects. (1) Risk neutrality: the typical participant did not learn to become risk averse, a contradiction of the hot stove effect. (2) Sensitivity to the transition probabilities that govern the Markov process. (3) Positive recency: the probability of a risky choice being repeated was higher after a win than after a loss. (4) Inertia: the probability of a risky choice being repeated following a loss was higher than the probability of a risky choice after a safe choice. These results can be described with a simple contingent sampler model, which assumes that choices are made based on small samples of experiences contingent on the current state. 相似文献

Recent studies have demonstrated motivation gains of low performing group members even beyond the level of an individual work baseline (e.g., Weber and Hertel, Journal of Personality and Social Psychology, 93:973–993, 2007). We expected that the underlying mechanisms of these motivation gains, i.e., social indispensability and social competition, are moderated by individuals’ gender. Moreover, these gender effects were assumed to be moderated by partner anonymity. Predictions were tested with mostly undergraduate German students (N?=?213) working in same-gender groups in a computer-supported environment. Results revealed that motivation gains due to social indispensability were more likely for women, whereas motivation gains due to social competition were more likely for men. Furthermore, women compared to men showed higher motivation gains in anonymous conditions compared to conditions with an acquainted partner. 相似文献

Previous research suggests that selective spatial attention is a determining factor for unconscious processing under continuous flash suppression (CFS), and specifically, that inattention toward stimulus location facilitates its unconscious processing by reducing the depth of CFS (Eo et al., 2016). The aim of our study was to further examine this modulation-by-attention model of CFS using a number priming paradigm. Participants (N = 26) performed a number comparison task on a visible target number (“compare target to five”). Prime-target pairs were either congruent (both smaller or larger than five) or incongruent. Spatial attention toward the primes was varied by manipulating the uncertainty of the primes’ location. Based on the modulation-by-attention model, we hypothesized the following: In trials with uncertain prime location, RTs for congruent prime-target pairs should be faster than for incongruent ones. In trials with certain prime location, RTs for congruent versus incongruent prime-target pairs should not differ. We analyzed our data with sequential Bayes factors (BFs). Our data showed no effect of location uncertainty on unconscious priming under CFS (BF0+ = 5.16). However, even visible primes only weakly influenced RTs. Possible reasons for the absence of robust number priming effects in our study are discussed. Based on exploratory analyses, we conclude that the numerical order of prime and target resulted in a response conflict and interfered with the predicted priming effect. 相似文献
