Does hunger influence judgments of female physical attractiveness?

To account for male preferences for female body weight following a consistent socio‐economic pattern, Nelson and Morrison (2005) proposed a social‐cognitive model based on the individual experience of resource scarcity. We replicated their studies showing that calorific dissatisfaction can influence preference for female body weight using a different dependent variable, namely photographic stimuli of women with known body weight and shape. Using this revised methodology, we found that operationalized intra‐individual resource scarcity affects preferences for body weight: 30 hungry male participants preferred figures with a higher body weight and rated as more attractive heavier figures than 31 satiated male participants. Hungrier men were also less likely to be influenced by cues for body shape, supporting extant cross‐cultural studies on female physical attractiveness. These findings corroborate those of Nelson and Morrison (2005) and are discussed in terms of how cultural contexts shape individual psychological experience as predicted by the theory of mutual constitution.     

Does momentary accessibility influence metacomprehension judgments? The influence of study—judgment lags on accessibility effects

In two experiments, we investigated momentary accessibility as a basis for metacomprehension judgments. Momentary accessibility has been cited as a major contributor to these judgments, yet the only previous investigation on the topic used judgments that were delayed a day after study, which have not been used in any other studies in the field and may be necessary for demonstrating accessibility-based effects. As expected, Experiment 1 demonstrated that the time between study and judgments moderates accessibility effects, with the relationship between judgments and access measures being substantially greater for delayed than for immediate judgments. Experiment 2 ruled out a plausible artifactual interpretation for accessibility effects on delayed judgments. In the discussion, we explore why study—judgment lags moderate accessibility effects.     

Does aging influence people's metacomprehension? Effects of processing ease on judgments of text learning

In 2 experiments, the authors investigated whether age-related differences exist in metacomprehension by evaluating predictions based on the ease-of-processing (EOP) hypothesis. According to this hypothesis, judgments of how well a text has been learned are based on how easily each text was processed; easier processing results in higher judgments. Participants read either sentence pairs or longer texts and judged their learning of each immediately afterward. Although an age-related difference in the use of processing ease in judgments was observed with sentence pairs, for longer texts older and younger adults' judgments were similarly related to processing ease. In both experiments, age equivalence was also evident in the accuracy of the judgments at predicting performance on the criterion test. The overall pattern of results suggests that judging text learning remains largely intact with aging.     

Does negative mood influence self-report assessment of individual and relational measures? An experimental analysis

The present study was designed to test the influence of negative mood on the self-report of individual and relational correlates of depression and marital distress. The authors applied a combined experimental mood induction procedure, based on music, autobiographical recall, and environmental manipulation. Results showed that the mood manipulation was effective, and the depressed Mood Induction Procedure (MIP) and neutral MIP groups did not differ in their self-rated measures of the above-mentioned variables. In conclusion, the authors argue that these measures are generally insensitive to depressed mood, providing an important contribution to this literature.     

Does visual experience influence the spatial distribution of auditory attention?

Sighted individuals are less accurate and slower to localize sounds coming from the peripheral space than sounds coming from the frontal space. This specific bias in favour of the frontal auditory space seems reduced in early blind individuals, who are particularly better than sighted individuals at localizing sounds coming from the peripheral space. Currently, it is not clear to what extent this bias in the auditory space is a general phenomenon or if it applies only to spatial processing (i.e. sound localization). In our approach we compared the performance of early blind participants with that of sighted subjects during a frequency discrimination task with sounds originating either from frontal or peripheral locations. Results showed that early blind participants discriminated faster than sighted subjects both peripheral and frontal sounds. In addition, sighted subjects were faster at discriminating frontal sounds than peripheral ones, whereas early blind participants showed equal discrimination speed for frontal and peripheral sounds. We conclude that the spatial bias observed in sighted subjects reflects an unbalance in the spatial distribution of auditory attention resources that is induced by visual experience.     

The influence of mood on the search for supporting versus conflicting information: dissonance reduction as a means of mood regulation?

Focusing on similarities between the mood regulation approach and dissonance theory, this article addresses the interplay between dissonance and mood by examining how individuals search for information after making a decision while under the influence of positive versus negative mood. Study 1 suggested that negative mood increased the preference for consonant over dissonant information after decisions, whereas positive mood led to a more balanced information search. In Study 2, participants in negative mood rated consonant information as more pleasant and dissonant information as more annoying than participants in positive mood. In addition, the results suggested that mood regulation processes took place. In Study 3, the findings from Study 1 were replicated with a paradigm in which higher stakes were involved.     

Does the nature of the experience influence suggestibility? A study of children's event memory

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects.     

Does selective attention influence the octave illusion?

The octave illusion occurs when each ear receives a sequence of tones alternating by one octave, but with different frequencies in each ear. Most listeners report a high pitch in one ear alternating with a low pitch in the opposite ear. Deutsch and Roll proposed an influential suppression model of the illusion in which the pitch is determined by ear dominance, while the location of this pitch is determined by high-frequency dominance. Deutsch later suggested that this unusual division between 'what' and 'where' mechanisms is facilitated by sequential interactions within the eliciting sequence. A recent study has raised doubts about the suppression model and the role of sequential interactions in the illusion (Chambers et al, 2002 Journal of Experimental Psychology: Human Perception and Performance 28 1288-1302). Here, we examined whether this previous null effect of sequential interactions may have arisen because of uncontrolled influences of selective attention. The results reveal no evidence of a link between selective attention and sequential interactions, thus consolidating doubts about the validity of the suppression model.     

Does delaying judgments of learning really improve the efficacy of study decisions? Not so much

A widely held assumption in metamemory is that better, more accurate metamemory monitoring leads to better, more efficacious restudy decisions, reflected in better memory performance--we refer to this causal chain as the restudy selectivity hypothesis. In 3 sets of experiments, we tested this hypothesis by factorially manipulating metamemory monitoring accuracy and self-regulation of study. To manipulate monitoring accuracy, we compared judgments of learning (JOLs) made contemporaneously with a delayed retrieval attempt to JOLs either made at a delay without attempting retrieval or made immediately after study; in previous studies, delayed retrieval-based JOLs have robustly predicted recall with greater relative accuracy than have the other JOL types. To manipulate self-regulation of study, in Experiments 1A-1C and 2A-2C, we compared conditions in which participants' restudy selections were honored with conditions in which they were completely or randomly dishonored; in Experiments 3A-3C, we randomly honored or dishonored half of the restudy selections and half of the nonselections. Results revealed that the benefit of delayed, retrieval-based JOLs for final memory performance was due largely to the selection of more items for restudy rather than to better discriminations between items that would benefit more versus less from restudy. In most cases, gains in recall due to greater self-regulation of study did not increase with better monitoring accuracy; when they did, the effect was extremely small. The surprising conclusion was that restudy decisions were not very much more efficacious under conditions that yield greater monitoring accuracy than under those that do not.     

Does home internet use influence the academic performance of low-income children?

HomeNetToo is a longitudinal field study designed to examine the antecedents and consequences of home Internet use in low-income families (http://www.HomeNetToo.org). The study was done between December 2000 and June 2002. Among the consequences considered was children's academic performance. Participants were 140 children, mostly African American (83%), mostly boys (58%), and most living in single-parent households (75%) in which the median annual income was 15,000 (U.S. dollars) or less. Average age was 13.8 years. Ages ranged between 10 and 18 years, Internet use was continuously recorded, and multiple measures of academic performance were obtained during the 16-month trial. Findings indicated that children who used the Internet more had higher scores on standardized tests of reading achievement and higher grade point averages 6 months, 1 year, and 16 months later than did children who used it less. Older children used the Internet more than did younger children, but age had no effect on the nature or the academic performance benefits of Internet use. Implications for the digital "use" divide are discussed.     

Does exposure to ambient odors influence the emotional content of memories?

This study examined the effects of implicitly presented odors on the emotional content of memory narratives. Participants were exposed to low levels of perfumes or no odors while they reconstructed a memory from childhood and a recurrent dream. Narratives were analyzed for emotional content using the Linguistic and Inquiry Word Count program. Exposure to perfumes increased the percentage of positive emotion words used by participants in recalling both dreams and childhood memories. In addition, exposure to odors decreased the percentage of negative emotion words that men used in their narratives, whereas the opposite effect was found for women. Discussion focuses on gender differences in written emotional expression, possible ways by which perfumes may exert their effects, and the usefulness of using ambient odors and objective content analysis when studying emotions in memories.     

Does contingency awareness mediate the influence of emotional learning on the cueing of visual attention?

Previous research has indicated that conditioning depends on contingency awareness (CA). However, we argue that these studies have examined this issue under methodological conditions that might be insensitive to associative learning without CA. In the present study we examined the effect of an experimental manipulation of CA on attentive processing of classically conditioned stimuli, which is sensitive to associative learning with and without CA. We found that aversive conditioning with additional contingency instructions modulated visual attention, in the sense that the conditioned cues captured and held attention more strongly than the non-conditioned cues. Surprisingly, conditioning under conditions of restricted CA yielded a response pattern that was different from that under full CA. These findings suggest that conditioning with full and restricted CA can lead to qualitatively different effects on attention.     

Does handedness influence the strength of phantom limb illusions in the virtual reality box?

Subjects had to judge the size of a tactile stimulus held in the unseen hand, while a visible phantom hand representing that unseen hand held a tactile stimulus of same or different size. No asymmetries in interference effects were found that could be related to hand or handedness. The method lends itself to quantification of virtual reality box illusions and can be used to evaluate the role of experience and sources of variability in the strength of the illusion across subjects.     

Want information? How mood and performance perceptions alter the perceived value of information and influence information-seeking behaviors

Currently, it is not well understood when positive and negative moods would encourage and discourage the process of identifying and seeking out valuable information. Building upon the mood-as-a-resource hypothesis and the mood-behavior-model, this project reconciles mixed findings by investigating and finding support for the hypothesis that positive moods encourage seeking instrumental information when performance is perceived to be weak; whereas negative moods encourage it when performance is perceived to be strong. These effects are due to mood influencing the perceived value (i.e. instrumentality) of information and cannot be explained by arguing that mood altered the affective costs/benefits associated with the information. Overall, these results indicate that positive moods may help individuals acquire information to resolve an existing problem, whereas negative moods may help individuals acquire information when there is no apparent problem.     

Traditional prejudice and justice judgments: Does bias suppression moderate the relationship?

This research investigated how the relationship between prejudice and intergroup inequalities with justice judgments is modulated by individual differences in self-regulation of bias through suppression. The first study conducted among 170 White British adolescents revealed that the link between racism and intergroup inequality in justice judgments was moderated by bias suppression. Prejudice, bias suppression, and blatant as well as subtle justice judgments were assessed in a second study carried out with 103 Canadian White adolescents. Bias suppression moderated the link between racist beliefs toward Aboriginals and intergroup inequality in punitive rulings. Racism translated into intergroup inequality in the potential for rehabilitation, irrespective of the level of bias suppression. The role of bias suppression is discussed.     

Reply to William R. Ferrell’s paper “A model for realism of confidence judgments: Implications for underconfidence in sensory discrimination”

Ferrell’s decision-variable partition model and our subjective distance model belong to the same family of Thurstonial models. The subjective distance model is limited to sensory discrimination with the method of constant stimuli and rooted in such notions as discriminal dispersion and sense distance. Ferrell’s model is intended to be wider in scope and to apply to both cognitive and sensory tasks. Both models need supplementary assumptions to predict calibration phenomena. The point of departure for us is the fact that the model predicts under-confidence under “guessing” and the empirical finding that people are about 100% correct when they report “absolutely certain.” Ferrell makes assumptions about cutoffs on the decision variable. The respondent is assumed to adjust or not adjust cutoffs according to “cues to difficulty.” We disagree with Ferrell’s claim that the hard-easy effect is explained by the respondent’s failure to adjust cutoffs sufficiently when there is a change in level of difficulty, and argue that this amounts to little more than a translation of the hard-easy effect into the lingua of Ferrell’s decision-variable partition model. Our argument is that the hard-easy effect is a consequence of the post hoc division of items according to solution probability. In addition, error variance may contribute to regression effects that enlarge the hard-easy effect. Finally, in contrast to Ferrell’s position, we regard inference (cognitive uncertainty) and discrimination (sensory uncertainty) as different psychological processes. An understanding of calibration in these two areas requires separate models.
