Some determinants of remote behavioral history effects in humans

Undergraduates were exposed to a series of reinforcement schedules: first, to a fixed-ratio (FR) schedule in the presence of one stimulus and to a differential-reinforcement-of-low-rate (DRL) schedule in the presence of another (multiple FR DRL training), then to a fixed-interval (FI) schedule in the presence of a third stimulus (FI baseline), next to the FI schedule under the stimuli previously correlated with the FR and DRL schedules (multiple FI FI testing), and, finally, to a single session of the multiple FR DRL schedule again (multiple FR DRL testing). Response rates during the multiple FI FI schedule were higher under the former FR stimulus than under the former DRL stimulus. This effect of remote histories was prolonged when either the number of FI-baseline sessions was small or zero, or the time interval between the multiple FR DRL training and the multiple FI FI testing was short. Response rates under these two stimuli converged with continued exposure to the multiple FI FI schedule in most cases, but quickly differentiated when the schedule returned to the multiple FR DRL.     

Factors influencing infants’ ability to update object representations in memory

Remembering persisting objects over occlusion is critical to representing a stable environment. Infants remember hidden objects at multiple locations and can update their representation of a hidden array when an object is added or subtracted. However, the factors influencing these updating abilities have received little systematic exploration. Here we examined the flexibility of infants’ ability to update object representations. We tested 11-month-olds in a looking-time task in which objects were added to or subtracted from two hidden arrays. Across five experiments, infants successfully updated their representations of hidden arrays when the updating occurred successively at one array before beginning at the other. But when updating required alternating between two arrays, infants failed. However, simply connecting the two arrays with a thin strip of foam-core led infants to succeed. Our results suggest that infants’ construal of an event strongly affects their ability to update memory representations of hidden objects. When construing an event as containing multiple updates to the same array, infants succeed, but when construing the event as requiring the revisiting and updating of previously attended arrays, infants fail.     

American-Japanese Differences in Multiscalar Intensity Ratings of Universal Facial Expressions of Emotion

This study reanalyzes American and Japanese multiscalar ratings of universal facial expressions originally collected by Matsumoto (1986), of which only single emotion scales were analyzed and reported by Matsumoto and Ekman (1989). The nonanalysis of the entire data set ignored basic and important questions about the nature of judgments of universal facial expressions of emotion. These were addressed in this study. We found that (1) observers in both cultures perceived multiple emotions in universal facial expressions, not just one; (2) cultural differences occurred on multiple emotion scales for each expression, not just the target scale; (3) the directions of those differences differed according to the rating scale used and the expression being observed; and (4) no underlying dimension was evidenced that would account for these differences. These findings raise new questions about the nature of the judgment process and the role of judgment studies in supporting the universality thesis, the bases of which need to be explored in future research and incorporated in future theories of emotion and universality.     

The Contribution of Individualism vs. Collectivism to Cross-national Differences in Display Rules

Despite the fact that display rules are an important concept of theories of emotion and contemporary psychology, relatively little cross-cultural research has been done on them. This study examined cross-national differences in display rules of emotion, and investigated the degree to which those differences could be attributed to Individualism and Collectivism (IC) measured on the individual level. Participants in the US, Japan, South Korea, and Russia completed a comprehensive measure of display rules assessing behavioral tendencies for seven universal emotions in four social contexts in two rating domains. They also completed Matsumoto et al .'s (1997) Individualism–Collectivism Interpersonal Assessment Inventory. The results confirmed the existence of cross-national differences in IC and display rules, and indicated that IC and display rules were correlated. Significant differences between the countries remained even after IC was controlled for, and effect size analyses comparing cross-national differences when IC was controlled and not indicated that IC accounted for approximately 30% of the effect sizes related to cross-national differences. This study is unique in that it not only used the concept of IC to explain and predict differences; it also quantitatively assessed the degree to which IC contributed to those differences. These findings are discussed in terms of the utility of the IC concept to understanding cross-cultural and cross-national differences in emotion.     

Self-reported expression and experience of triumph across four countries

Recent studies have suggested the existence of the emotion of triumph by documenting how its nonverbal signals are displayed and identified across cultures. The current study contributes to this literature by providing additional convergent evidence about the expression of triumph by examining self-reported expressions of triumph from participants from Japan, Russia, Serbia, and the U.S. Self-reported behavioral expressions of triumph were consistent with three factors previously found to be associated with the triumph expression (Expansion, Aggression, Attention), with the exception of a finding on one scale in one country. The Japanese were prone to report greater regulation compared to the experience of triumph, whereas Americans and Serbians reported relatively greater experience compared to regulation. Across countries, Aggression was positively correlated with self-reported experience. The self-reported expressions of triumph partially corresponded with nonverbal reactions that had been identified as triumph in previous research.     

Linguistic Cues of Deception Across Multiple Language Groups in a Mock Crime Context

A recent study showed that specific linguistic and grammatical features of a technique commonly referred to as statement analysis are applicable across different language groups. One limitation of that study was that it used an eyewitness crime video paradigm, which might be different from writing a statement after committing an actual criminal act. We remedied that limitation by using a mock crime paradigm. In this study, three language groups (English, Spanish, and Chinese) produced statements after committing a mock crime, taking a check, in an experimental context. Certain linguistic features significantly discriminated truths from lies similarly across the different language groups, suggesting that statement analysis might be applicable as a reliable indicator of deception across languages.

Culture, context, and behavior

In this article I propose a model that posits three major sources of influence on behavior-basic human nature (via universal psychological processes), culture (via social roles), and personality (via individual role identities) and argue that individual behaviors are the products of the interaction between the three. I discuss how culture emerges from the interaction of basic human nature and the ecological contexts in which groups exist, and how social roles are determined by culture-specific psychological meanings attributed to situational contexts. The model further suggests that situational context moderates the relative contributions of the three sources in influencing behavior. I provide examples of apparent contradictory findings in the study of emotion that can be explained by the model proposed.     

Rorschach Comprehensive System data for a sample of 190 Japanese nonpatient children at five ages

This study is a part of our series of studies of nonpatient, Japanese children. In total, 346 children were administered the Rorschach. Thirty-two children had fewer than 10 responses, 112 children had more than 10 but fewer than 14 responses, and 12 children were maladjusted or mentally retarded, for a total of 156. In this study, we analyzed the remaining 190 children not excluded by the above criteria in the following age groups: 5 years (n = 24), 8 years (n = 43), 9 years (n = 42), 12 years (n = 42), and 14 years (n = 39). Japanese children showed few responses generally, with an average of 18 ~ 20 responses. In addition to having fewer responses, other features of Japanese children are high Lambda, low EA, very high X-%, and low X+%. The fact that the Rorschach test depends on verbal expression may be one factor in all these features, and we should consider this study in view of these Japanese cultural factors. Interrater reliability findings and Rorschach Comprehensive System (CS; Exner, 1995; Matsumoto, 2003; Matsumoto et al., 2002) data are presented.     

Differences in adrenocortical secretory and gene expression responses to stimulation in vitro by ACTH or prolactin between high- and low-avoidance Hatano rats

Rats of the Hatano high-avoidance (HAA) and low-avoidance (LAA) strains have been genetically selected on the basis of their two-way active avoidance behavior, and have different endocrine responses to stress. The present study focused on the adrenal steroid hormone responses of the Hatano strains and identifies differences in regulation of the adrenal cortex in vitro of HAA and LAA rats. Although incubation with prolactin (PRL) and/or adrenocorticotrophic hormone (ACTH) resulted in a dose-dependent increase of corticosterone and progesterone release by adrenal cells from both HAA and LAA male rats, the responses were markedly increased for adrenal cells from LAA rats as compared with HAA rats. This finding suggested that adrenal glands of HAA rats are less sensitive to PRL and/or ACTH than adrenals from LAA rats. Several possible intra-adrenal regulators were investigated. The basal level of expression of steroidogenic acute regulatory protein (StAR) and the long form of the PRL receptor (PRLR-L) mRNAs was higher in adrenals of LAA rats. ACTH treatment of adrenal cells from HAA rats resulted in statistically significant increases in melanocortin receptor 2 (MC2R) mRNA expression, while neither ACTH nor PRL altered MC2R mRNA expression in adrenal cells of LAA rats. Conversely, the increase in PRLR-L mRNA expression induced by PRL was observed only in adrenal cells from LAA rats. Treatment of adrenal cells with PRL and/or ACTH increased the expression of StAR and CYP11A1 mRNAs for both Hatano strains. However, the induction of StAR mRNA expression was higher in LAA rats, but the CYP11A1 response was lower. These findings indicate that adrenal cells of the LAA strain have higher sensitivity to secretagogues than those of the HAA strain. These results suggest that PRL may also be important in stimulating secretion of adrenal steroid hormones.
