Exposed intestines and contaminated cooks: Sex,stress, & satiation predict disgust sensitivity

An evolutionary perspective predicts that the intensity of the disgust response should depend on the ancestral costs and benefits of coming into contact with disease vectors. Previous research advanced the compensatory behavioral prophylaxis hypothesis: progesterone-induced immunosuppression should be accompanied by increased disgust and contaminant-avoidance. However, extant data do not address whether factors other than progesterone-induced immunosuppression also trigger heightened disgust. The current study delineates two competing prophylaxis hypotheses and adjudicates between them by testing whether stress and satiation, which shift the costs and benefits of prophylactic behavior but are unrelated to progesterone-induced immunosuppression, predict disgust sensitivity. Results revealed a sex–stress–satiation interaction in predicting Disgust Scale-Revised (DS-R) scores. This study provides evidence of a broader system of compensatory prophylaxis, illuminates the functional basis of facultative shifts in disgust, and presents conceptual and statistical analyses for more cleanly cleaving the psychology of disgust at its natural joints.     

Conditioned taste aversion is enhanced when the unconditioned stimulus is presented in a different context

Using a conditioned taste aversion procedure with rats as the subjects, two experiments examined the effect of presenting a conditioned stimulus (CS saccharin solution) in one context followed by an unconditioned stimulus (US LiCl) in a different context. Experiment 1 showed that animals which received the above-mentioned procedure (Group D) showed a more marked conditioned aversion to the CS than animals which were given both the CS and the US in the same context (Group S). Experiment 2 found that in both Group D and Group S, aversion to the CS increased when the subjects were exposed to the conditioned context after the conditioning. These findings supported the argument that the strength of the CS-US association acquired during conditioning is compared with that of the context-US to determine the magnitude of aversion revealed to the CS.     

Context Effects on Musical Chord Categorization: Different Forms of Top‐Down Feedback in Speech and Music?

A critical issue in perception is the manner in which top-down expectancies guide lower level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting participants with major/minor triad continua after brief musical contexts. Two experiments yielded results that differed from classic results in speech perception. In speech, context generally expands the category of the expected stimuli. We found the opposite in music: The major/minor boundary shifted toward the expected category, contracting it. Together, these experiments support the hypothesis that musical expectancy can feed back to affect lower-level perceptual processes. However, it may do so in a way that differs fundamentally from what has been seen in other domains.     

Introduction: Constructivism and social constructionism in the career field

The impact of constructivism and social constructionism upon vocational psychology has often been through the use of the more generic “constructivism.” In this article constructivism is distinguished by its focus on how the individual cognitively engages in the construction of knowledge from social construction which claims that knowledge and meaning are historically and culturally constructed through social processes and action. The considerable ambiguity in the use of these terms is also discussed. Their contributions, challenges, and opportunities to the career field’s dominant discourses are examined: the dispositions discourse, the contextualizing discourse, the subjectivity and narrative discourse, and the process discourse. Broader challenges and opportunities for the field are also noted. The historical construction of knowledge, concern with language, action, and process problematize traditional understandings of career. They raise opportunities to question fundamental assumptions, focus on context, culture, the person-environment interaction, and practice.     

Sitting on the word “chair”: Behavioral support, contextual cues, and the literal use of symbols

Recent work from an embodied-cognition perspective suggests that symbolic understanding involves bodily actions. Indeed, laboratory evidence and cultural phenomena such as magic rituals and symbolic aggression show that the behaviors evoked by a word and its referent can be quite similar to each other. In other circumstances, however, words and objects fail to display the expected degree of functional equivalence: Although we regularly sit on chairs, for example, we normally do not sit on the word “chair.” In two experiments we evaluated whether functional equivalence between word and object depended on behavioral support and contextual stimuli, as suggested by some Pavlovian views of symbolic performance. Children spent more or less time seated on a token of the word “chair,” depending on supports for sitting and background stimuli. This study may help to understand the determinants of response frequency in symbolic understanding.     

Effects of Pinyin and First Language Words in Learning of Chinese Characters as a Second Language

This study examined the roles of pinyin and English words as stimulus prompts in the learning of Chinese characters. Recall for naming of English words and pronunciation was enhanced under conditions in which each character was presented first and its prompts were given as feedback, in contrast to simultaneous presentation conditions. Pronunciation was also recalled more in the written pinyin conditions than the verbal pronunciation conditions. These data were interpreted in terms of (a) interference which can occur when learners attend to multiple inputs simultaneously, and (b) the beneficial effects of attending to character prior to their prompts. It was concluded that the presentation of a character first and the provision of its associated prompts as a feedback improves learning.     

The colour red affects time perception differently in different contexts

Previous studies have found that psychological and behavioural functions of the colour red vary according to context. In this research, we used the verbal estimation paradigm to determine if the colour red affects individuals' perception of interval duration. In our results, perceived duration was shorter in a red condition than in a blue one; additionally, only in the red condition, perceived duration was shorter in an online dating context than in an online interviewing context. The contribution and limitations of this study and future research directions are discussed.     

Assessment and treatment of automatically reinforced self‐induced emesis

Frequent emesis can cause substantial deleterious effects to a child's health and environment. We conducted a functional analysis of a 3‐year‐old girl's self‐induced emesis and confirmed that emesis was maintained by automatic reinforcement. In a reversal design, we evaluated the efficacy of implementing response blocking at 100% and 50% treatment integrity levels on both attempts and successful production of emesis. One hundred percent blocking, but not 50% blocking, was successful in reducing attempts and emesis below baseline levels.     

Predicting toddler temperamental approach-withdrawal: Contributions of early approach tendencies,parenting behavior,and contextual novelty

Research suggests that temperamental approach-withdrawal is subject to parenting influences, but few studies have explored how specific parenting behaviors and contextual novelty contribute to the observed pattern of effects. The present study examined associations between infant temperamental approach, mother behavior while introducing novel objects (12 months) and temperamental approach-withdrawal in toddlerhood (18 months) in a sample of 132 infants (68 males). Maternal positive affect predicted more toddler approach-withdrawal for high-approach infants and maternal stimulation predicted less toddler approach-withdrawal for low-approach infants; however, these patterns varied with intensity of novelty in both parenting and toddler outcome contexts. Thus, maternal behavior may lead to stronger associations between earlier and later measures of approach-withdrawal; however, these effects are tied to contexts of measurement.     

Overconfidence at the Keyboard: Confidence and Accuracy in Interpreting Affect in E‐Mail Exchanges

Gesture, voice, expression, and context add richness to communications that increase chances of accurate interpretation. E‐mails lack much of this richness, leading readers to impose their own richness. Three experiments tested the effect of communicator relationship and availability of context on e‐mail writer and reader confidence levels and accuracy. Effects of nonverbal and verbal behavior were also investigated. Results showed that confidence levels for both writers and readers were high, yet somewhat unwarranted based on accuracy rates. Further, writers had more confidence that friends would correctly interpret e‐mails than strangers, although friends showed no more accuracy. Findings suggest that reliance upon friendship and context, as well as verbal and nonverbal cues, to interpret emotion in e‐mail is ineffective, sometimes detrimental.
