Valence and Arousal Ratings for Velten Mood Induction Statements

Participants rated 84 statements adapted from Velten's original mood induction statements—designed to induce positive and negative mood—on two dimensions of emotion (valence and arousal), using the Self Assessment Manikin (SAM) (P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Fifty-two of these Velten positive, negative, and neutral statements yielded SAM valence ratings that were consistent with Velten's previous valence designation (E. Velten, 1968). Reliability analyses for the positive, negative, and neutral statements indicated a high level of internal consistency in the three statement groups. Arousal and valence ratings of the statements were positively correlated. Related issues concerning differences in rating verbal versus visual emotional stimuli and recommendations for future work to improve the validity of Velten's mood induction statements are addressed.     

Planned Straight or Biased to Be So? The Influence of Visual Feedback on Reaching Movements

Abstract

Behavioral studies consistently find that subjects move their hand along straight paths despite considerations that suggest reaches should be curved. Literature on this topic makes it clear that the experimentally displayed feedback influences how subjects reach. Could the standard visual feedback, a displayed cursor, explain the lack of path curvature in experimental results? To address this question, we conducted three experiments to examine reach behavior in the absence of the standard visual feedback. In the first experiment, we found significant increases in curvature as visual feedback was progressively extinguished across groups. A second experiment revealed that practiced reaches became curved after the standard visual feedback was removed. A final experiment found that subjects’ reaches made before and after a brief display of visual feedback were similar, indicating a preference for specific curved trajectories. Our results suggest that the consistently straight reaches often observed could be due to a bias to move the displayed cursor straight, which when removed reveal subject-specific preferences for reaches that are often curved.     

Homophone effects in visual word recognition depend on homophone type and task demands.

This experiment examined how the characteristics of homophones and their mates influence homophone effects, as a function of task demands. Two types of homophones were presented: 1) low-frequency homophones with higher-frequency mates that are not animal names (e.g., maid--made), and 2) low-frequency homophones with mates that are, on average, of equivalent frequency and are animal names (e.g., foul--fowl). We observed a double dissociation: In the lexical decision task (LDT), there was a homophone effect for the first type of homophones but not for the second, whereas in the semantic categorization task (SCT) the opposite was true. These results suggest that in these tasks the effects of homophony arise when the homophone's mate creates competition in terms of the type of processing emphasized in the task, namely, orthographic processing in the LDT and semantic processing in the SCT.     

Anti-fat prejudice among children: The “mere proximity” effect in 5-10 year olds

Research has shown that average-weight individuals are derogated when viewed next to overweight background individuals, rather than next to average-weight background individuals (Hebl, M. R., & Mannix L. M. (2003). The weight of obesity in evaluating others: A mere proximity effect. Personalilty and Social Psychology Bulletin, 29, 28-38). The aim of the present investigation was to determine whether this mere proximity effect would be obtained among children, and to determine how participant gender, target character gender and size, and background character size affect this finding. Eighty-nine children between 5 and 10 years old indicated whether they would like to be friends with a target character, who was either male or female and average-weight or overweight. The target was presented with four other background characters of the same gender, all of whom were either average-weight or overweight. The results showed that overall, overweight targets were liked significantly less than average-weight targets, though this effect was moderated by target gender. Furthermore, participants liked average-weight female targets significantly less when they were presented with overweight background characters, and liked overweight female targets significantly less when they were presented with average-weight background characters. This was not the case for male targets. These findings support the mere proximity effect for female targets and demonstrate that this effect is present in children as young as five years of age. The implications are discussed with regards to obesity stigma.     

Effects of relative embodiment in lexical and semantic processing of verbs

Research examining semantic richness effects in visual word recognition has shown that multiple dimensions of meaning are activated in the process of word recognition (e.g., Yap et al., 2012). This research has, however, been limited to nouns. In the present research we extended the semantic richness approach to verb stimuli in order to investigate how verb meanings are represented. We characterized a dimension of relative embodiment for verbs, based on the bodily sense described by Borghi and Cimatti (2010), and collected ratings on that dimension for 687 English verbs. The relative embodiment ratings revealed that bodily experience was judged to be more important to the meanings of some verbs (e.g., dance, breathe) than to others (e.g., evaporate, expect). We then tested the effects of relative embodiment and imageability on verb processing in lexical decision (Experiment 1), action picture naming (Experiment 2), and syntactic classification (Experiment 3). In all three experiments results showed facilitatory effects of relative embodiment, but not imageability: latencies were faster for relatively more embodied verbs, even after several other lexical variables were controlled. The results suggest that relative embodiment is an important aspect of verb meaning, and that the semantic richness approach holds promise as a strategy for investigating other aspects of verb meaning.     

Social transmission of Pavlovian fear: fear-conditioning by-proxy in related female rats

Pairing a previously neutral conditioned stimulus (CS; e.g., a tone) to an aversive unconditioned stimulus (US; e.g., a foot-shock) leads to associative learning such that the tone alone will elicit a conditioned response (e.g., freezing). Individuals can also acquire fear from a social context, such as through observing the fear expression of a conspecific. In the current study, we examined the influence of kinship/familiarity on social transmission of fear in female rats. Rats were housed in triads with either sisters or non-related females. One rat from each cage was fear conditioned to a tone CS+ shock US. On day two, the conditioned rat was returned to the chamber accompanied by one of her cage mates. Both rats were allowed to behave freely, while the tone was played in the absence of the foot-shock. The previously untrained rat is referred to as the fear-conditioned by-proxy (FCbP) animal, as she would freeze based on observations of her cage-mate’s response rather than due to direct personal experience with the foot-shock. The third rat served as a cage-mate control. The third day, long-term memory tests to the CS were performed. Consistent with our previous application of this paradigm in male rats (Bruchey et al. in Behav Brain Res 214(1):80–84, 2010), our results revealed that social interactions between the fear conditioned and FCbP rats on day two contribute to freezing displayed by the FCbP rats on day three. In this experiment, prosocial behavior occurring at the termination of the cue on day two was significantly greater between sisters than their non-sister counterparts, and this behavior resulted in increased freezing on day three. Our results suggest that familiarity and/or kinship influences the social transmission of fear in female rats.     

Why are women more religious than men? Testing the explanatory power of personality theory among undergraduate students in Wales

This study tests the explanatory power of personality-based psychologically grounded theories to account for the well-established finding within the psychology of religion that within Christian and post-Christian contexts women are more religious than men. A sample of 1682 undergraduate students in Wales completed the short form of the Eysenck Personality Questionnaire Revised together with the adult form of the Francis Scale of Attitude towards Christianity and measures of frequency of church attendance, and frequency of personal prayer. These data confirm that women record higher levels of religiosity and lower levels of psychoticism, and demonstrate that psychoticism is the strongest predictor of individual differences in religiosity. Multiple-regression analyses show that, when individual differences in personality are taken into account, biological sex adds no further impact on religiosity. This finding suggests that higher levels of religiosity among women may be interpreted as a function of basic psychological differences in levels of psychoticism rather than as a sociological function of being female.     

Loose Connections and Liberal Theology: Blurring the Boundaries in Two Church‐Based Communities of Spiritual Practice

We used a mixed methods approach—including ethnographic fieldwork, interviews, and a survey—to study two innovative Christian contemplative worship services housed in a mainline Protestant congregation in a midwestern city. These services employed boundary‐blurring practices designed to attract the “de‐churched”—those who had been involved in a Christian congregation in the past but who had at some point disengaged from organized religion. Though attracting some formerly de‐churched participants, these services were far more successful in attracting several other constituencies united by their liberal theology and by a preference for loose connections. We argue that these worship services are best understood as thriving communities of sustained spiritual practice where contemplative rituals sacralize both theistic and extra‐theistic, Christian and non‐Christian, symbols and beliefs.     

How surveillance begets perceptions of dishonesty: the case of the counterfactual sinner

Three studies support the hypothesis that observers' impressions of actors reflect not only what actors do but also what they can easily be imagined doing. Participants in Studies 1 and 2 observed a 10-year-old boy take a math test in a context in which the incentive to cheat and the constraints against cheating varied. When the incentive to cheat was high but the likelihood of getting caught was also high, observers perceived a target who resisted the temptation to cheat as less honest than the average boy. This effect was not found when the incentive to cheat was low, which suggests that its occurrence under high temptation resulted from observers in that condition generating the counterfactual thought that the target would have cheated had the likelihood of detection been low. Study 3 further supported the link between spontaneous counterfactual thought and inferences of dishonesty. The implications of the counterfactual correspondence bias are discussed.
