Maternal self-efficacy, knowledge of infant development, sensory sensitivity, and maternal response during interaction

When their infants were 6 months of age, mothers were assessed for self-efficacy (low, moderate, and high illusory control) and knowledge of infant development to determine their impact on mothers' behavioral sensitivity and affect during a feeding task at 9 months (N=70). Mothers' sensory sensitivity to digital images of infants' negative and positive expressions assessed in a signal detection task at 6 months was hypothesized to mediate this relation. Mothers with moderate illusory control exhibited greatest behavioral sensitivity and positive affect. Low knowledge was associated with reduced sensitivity for mothers with low illusory control only. When viewing the negative expression, mothers with moderate illusory control and high knowledge exhibited greatest sensory sensitivity, and mothers with high illusory control and moderate/high knowledge were least sensitive. Although sensory sensitivity was not a mediating variable, its relation to both illusory control and subsequent maternal measures during feeding was informative. Although greater sensory sensitivity predicted more sensitive behavior and more positive affect, only for maternal affect was the relation independent of illusion of control effects.     

A Bayesian view of covariation assessment

When participants assess the relationship between two variables, each with levels of presence and absence, the two most robust phenomena are that: (a) observing the joint presence of the variables has the largest impact on judgment and observing joint absence has the smallest impact, and (b) participants' prior beliefs about the variables' relationship influence judgment. Both phenomena represent departures from the traditional normative model (the phi coefficient or related measures) and have therefore been interpreted as systematic errors. However, both phenomena are consistent with a Bayesian approach to the task. From a Bayesian perspective: (a) joint presence is normatively more informative than joint absence if the presence of variables is rarer than their absence, and (b) failing to incorporate prior beliefs is a normative error. Empirical evidence is reported showing that joint absence is seen as more informative than joint presence when it is clear that absence of the variables, rather than their presence, is rare.     

addressing career issues online: perceptions of counselor education professionals

The Internet is the latest arena in which counseling services are available for a variety of issues. This study surveyed counselor education professionals about their perceptions regarding the use of online counseling to address various mental health issues including career counseling. It also examined their perceptions about 3 formats of online counseling: e‐mail, text‐based chat, and videoconferencing. Results indicated that counselor education professionals were open to the use of online counseling to address career issues. The implications for the practice of online career counseling and for the training of counselors are discussed.     

An analysis of a cross-cultural personality inventory: the IPIP Big-Five factor markers in Croatia

In this article, we describe the factor structure in both self-reports and peer ratings of the items in a cross-cultural Big-Five inventory in Croatia. Using 2 versions of an inventory developed from the International Personality Item Pool (IPIP; Goldberg, 1999), this is one of the first cross-national analyses of these IPIP measures. A large sample of university students (N = 519) used the translated Croatian version of the 100-item IPIP Big Five inventory to describe themselves, and they were also described by 515 of their acquaintances on the same instrument. In separate analyses of both self-reports and peer ratings, the 100-item and 50-item versions of these IPIP measures showed clear Five-factor orthogonal structures that were nearly identical to the American structure. These factors were strongly related on a one-to-one basis with those derived from a Croatian translation of Goldberg's (1992) bipolar rating scales.     

Conflicting social motives in negotiating groups

Negotiators' social motives (cooperative vs. individualistic) influence their strategic behaviors. In this study, the authors used multilevel modeling and analyses of strategy sequences to test hypotheses regarding how negotiators' social motives and the composition of the group influence group members' negotiation strategies. Four-person groups negotiating a 5-issue mixed-motive decision-making task were videotaped, and the tapes were transcribed and coded. Group composition included 2 homogeneous conditions (all cooperators and all individualists) and 3 heterogeneous conditions (3 cooperators and 1 individualist, 2 cooperators and 2 individualists, 1 cooperator and 3 individualists). Results showed that cooperative negotiators adjusted their use of integrative and distributive strategies in response to the social-motive composition of the group, but individualistic negotiators did not. Results from analyses of strategy sequences showed that cooperators responded more systematically to others' behaviors than did individualists. They also redirected the negotiation depending on group composition.     

Further validation of the gratitude, resentment, and appreciation test (GRAT)

The authors conducted this study to further validate the revised short form of the Gratitude, Resentment, and Appreciation Test by investigating the relationship between GRAT-measured gratitude and two other constructs: (a) spiritual transcendence and (b) materialism. As predicted, both the GRAT and its subscales correlated positively with a measure of spiritual transcendence and negatively with a measure of materialism.     

Signal transduction mechanisms within the entorhinal cortex that support latent inhibition of cued fear conditioning

Latent inhibition is a phenomenon by which pre-exposure to a conditioned-stimulus (CS), prior to subsequent pairings of that same CS with an unconditioned-stimulus (US), results in decreased conditioned responding to the CS. Previous work in our laboratory has suggested that the entorhinal cortex is critically involved in the establishment of latent inhibition of cued fear conditioning. Furthermore, utilizing systemic pharmacology, we have demonstrated a role for of NMDA receptors, protein kinase A (PKA), and mitogen activated protein kinase (MAPK, also known as ERK) in latent inhibition of cued fear conditioning, but until now, where these cell signaling cascades are critically activated during latent inhibition of cued fear was unknown. Here, we use direct drug infusion to demonstrate that cell signaling via NMDA receptors, the cAMP/PKA pathway, and the MAPK pathway within the entorhinal cortex are critically involved in latent inhibition of cued fear conditioning. In the present study, CS pre-exposed mice received 20 CS pre-exposures 24h prior to two pairings of the same CS with a 0.53 mA foot shock US, while control animals receive no pre-exposure to the CS. The NMDA antagonist APV (0.25 or 2.5 microg/side), the cAMP inhibitor Rp-cAMP (1.8 or 18.0 microg/side), or the MAPK inhibitor U0126 (0.1 or 1.0 microg/side) were directly infused into the entorhinal cortex prior to pre-exposure. All three drugs produced dose-dependent disruptions in latent inhibition of cued fear conditioning. Importantly, none of the drugs had any effect on cued fear conditioning when administered on training day, suggesting that the effects of each of the drugs were specific to CS pre-exposure. These results are discussed in relation to the potential mechanisms of plasticity that support latent inhibition of cued fear conditioning.     

Internet versus paper‐and‐pencil survey methods in psychological experiments: Equivalence testing of participant responses to health‐related messages

Despite experiments being increasingly conducted over the Internet, few studies have tested whether such experiments yield data equivalent to traditional methods' data. In the current study, data obtained via a traditional sampling method of undergraduate psychology students completing a paper‐and‐pencil survey (N = 107) were compared with data obtained from an Internet‐administered survey to a sample of self‐selected Internet‐users (N = 94). The data examined were from a previous study that had examined the persuasiveness of health‐related messages. To the extent that Internet data would be based on a sample at least as representative as data derived from a traditional student sample, it was expected that the two methodologies would yield equivalent data. Using formal tests of equivalence on persuasion outcomes, hypotheses of equivalence were generally supported. Additionally, the Internet sample was more diverse demographically than the student sample, identifying Internet samples as a valid alternative for future experimental research.     

Religious Identity and Cultural Diversity: Exploring the Relationships Between Religious Identity,Sexism, Homophobia,and Multicultural Competence

In this article, the authors present the results from a national study investigating the relationships between religious identity, sexism, homophobia, and multicultural competence. Participants were 111 randomly sampled counseling professionals and graduate students. The results indicated a relationship between religious identity and various aspects of valuing cultural diversity, including sexism, homophobia, and multicultural competence. Implications of the role of religion and religious identity in counseling are discussed, and suggestions for future research are provided.     

THIS ARTICLE HAS BEEN RETRACTED: Enumeration of objects and substances in non‐human primates: experiments with brown lemurs (Eulemur fulvus)

Both human infants and adult non‐human primates share the capacity to track small numbers of objects across time and occlusion. The question now facing developmental and comparative psychologists is whether similar mechanisms give rise to this capacity across the two populations. Here, we explore whether non‐human primates’ object tracking abilities are subject to the same constraints as those of human infants. In particular, we examine whether one primate species, the brown lemur (Eulemur fulvus), also fails to represent and enumerate objects when they behave non‐rigidly or non‐cohesively. We presented lemurs with a series of expectancy violation studies involving simple 1 + 1 addition events in which we varied the entities to be enumerated. Like infants, lemurs successfully enumerated the two objects when those objects were rigid, cohesive individuals, but failed to enumerate similar‐looking non‐rigid piles of sand. In contrast to human infants, however, lemurs successfully enumerated non‐cohesive objects that broke into multiple pieces. These results are discussed in light of recent theories about object processing in human infants and adults.
