Effects of Attachment on Coping Efficacy,Career Decision Self‐Efficacy,and Life Satisfaction

This study examined attachment, self‐efficacy variables, and life satisfaction of 583 undergraduate students. The type of analysis used was structural equation modeling. Findings indicated that students with greater avoidant and anxious attachment patterns reported lower levels of career decision self‐efficacy and coping efficacy, which then had a positive relationship with life satisfaction. Implications for theory, research, and practice were provided.     

Victimized Children’s Adjustment Difficulties: The Role of Parenting Styles and Parents’ Childhood Peer Victimization Status

The purpose of the present study was to examine the role of parents’ childhood victimization status in the associations among parenting styles and victimized children’s depression and anxiety. Participants were 203 parents (86% mothers; M age = 43.75, SD = .76) and their children in the fourth or fifth grade (n = 203; 56% female; M age = 9.74, SD = .34). Children completed measures on peer victimization, their perceptions of their parents’ parenting styles, depression, and anxiety, while parents completed a measure on their childhood peer victimization while in elementary school. Parents’ childhood peer victimization status moderated relationships among authoritarian and permissive parenting styles and victimized children’s adjustment difficulties. These findings highlight the importance of considering parents’ experience of childhood peer victimization and its impact on their parenting styles and their children’s adjustment difficulties.     

Implications of Religious Identity Salience,Religious Involvement,and Religious Commitment on Aggression

Social identity can affect perceptions of external threats and the type of response elicited to those threats. Religion is a social identity with eternal group membership and revered beliefs and values; thus, religious identity salience, religious commitment, and religious involvement may have implications for aggressive responses to perceived threats to a person’s religious identity. In a sample of 176 Christians, Muslims, and Jews, we investigated whether people respond aggressively to collective threat as a function of religious identity salience, religious commitment, and religious involvement. Religious commitment was positively related to anger only when religious identity was salient. Religious involvement was negatively related to anger and hostility only when religious identity was salient. Religious identity salience appears to act as a moderator by either enhancing perceptions of threat or by activating internal religious beliefs and values.     

Influence of chronic corticosterone and glucocorticoid receptor antagonism in the amygdala on fear conditioning

Glucocorticoid receptor activation within the basolateral amygdala (BLA) during fear conditioning may mediate enhancement in rats chronically exposed to stress levels of corticosterone. Male Sprague-Dawley rats received corticosterone (400 microg/ml) in their drinking water (days 1-21), a manipulation that was previously shown to cause hippocampal CA3 dendritic retraction. Subsequently, rats were adapted to the fear conditioning chamber (day 22), then trained (day 23), and tested for conditioned fear to context and tone (day 25). Training consisted of two tone (20s) and footshock (500 ms, 0.25 mA) pairings. In Experiment 1, muscimol (4.4 nmol/0.5 microl/side), a GABAergic agonist, was microinfused to temporarily inactivate the BLA during training. Rats given chronic corticosterone showed enhanced freezing to context, but not tone, compared to vehicle-supplemented rats. Moreover, BLA inactivation impaired contextual and tone conditioning, regardless of corticosterone treatment. In Experiment 2, RU486 (0, 0.3, and 3.0 ng/0.2 microl/side) was infused on training day to antagonize glucocorticoid receptors in the BLA. Corticosterone treatment enhanced fear conditioning to context and tone when analyzed together, but not separately. Moreover, RU486 (3.0 ng/side) selectively exacerbated freezing to context in chronic corticosterone-exposed rats only, but failed to alter tone conditioning. Serum corticosterone levels were negatively correlated with contextual, not tone, conditioning. Altogether, these suggest that chronic corticosterone influences fear conditioning differently than chronic stress as shown previously. Moreover, chronic exposure to corticosteroids alters BLA functioning in a non-linear fashion and that contextual conditioning is influenced more than tone conditioning by chronic corticosterone and BLA glucocorticoid receptor stimulation.     

Searching for genetic influences on normal cognitive ageing

Differences in non-pathological cognitive ageing provide a useful case study for the opportunities and challenges facing cognitive science as it embraces advances in genetics. One replicated contributor to these differences is variability in the gene for apolipoprotein E. Genetic variations that influence neurodegenerative diseases, learning and memory, cardiovascular disease, and oxidative stress are among the candidates for influence on cognitive ageing differences. The area suffers the same problems as other domains in which quantitative trait loci are sought: uncertainty regarding the genetic architecture, unreliable strategies for candidate gene selection, lack of power leading to unreplicated findings, and poor characterisation of the phenotype. However, current progress in genetic knowledge, technology and informatics will contribute to progress in this important area.     

Phonological cues influence sex decisions about novel names

Investigations of first names in English have found that male and female names are distinguished by different phonological characteristics. This paper reports on findings that suggest native speakers of English rely on those same cues when making judgments about the sex of names with which they are unfamiliar. When presented with 40 novel, i.e., "invented" names, 25 university undergraduates judged one-syllable names and consonant-final names as male names; however, they judged two-syllable names and vowel-final names as female names. These findings indicate that certain phonological features are strong enough predictors of sex that they can be used to designate sex even with names never before encountered.     

Recollection rejection: false-memory editing in children and adults

Mechanisms for editing false events out of memory reports have fundamental implications for theories of false memory and for best practice in applied domains in which false reports must be minimized (e.g., forensic psychological interviews, sworn testimony). A mechanism posited in fuzzy-trace theory, recollection rejection, is considered. A process analysis of false-memory editing is presented, which assumes that false-but-gist-consistent events (e.g., the word SOFA, when the word COUCH was experienced) sometimes cue the retrieval of verbatim traces of the corresponding true events (COUCH), generating mismatches that counteract the high familiarity of false-but-gist-consistent events. Empirical support comes from 2 qualitative phenomena: recollective suppression of semantic false memory and inverted-U relations between retrieval time and semantic false memory. Further support comes from 2 quantitative methodologies: conjoint recognition and receiver operating characteristics. The analysis also predicts a novel false-memory phenomenon (erroneous recollection rejection), in which true events are inappropriately edited out of memory reports.     

LY354740, an mGlu2/3 receptor agonist as a novel approach to treat anxiety/stress

Metabotropic glutamate (mGlu) receptors, which include mGlu1-8 receptors, are a heterogeneous family of G-protein coupled receptors (GPCRs) that function to modulate neuronal excitation and plasticity via pre-synaptic, post-synaptic and glial mechanisms. Agonists for group II mGlu receptors (mGlu2 and mGlu3), such as LY354740, have been shown to suppress enhanced glutamatergic excitations in brain synapses known to be involved in the expression of fear/anxiety in animals and humans. Systemic administration of LY354740 increases open-arm time in the elevated plus maze in mice under conditions of moderate to severe stress, blocks the expression but not development of fear-potentiated startle in rats, prevents lactate-induced panic-like responses in panic-prone rats, and attenuates certain physiological, behavioral, and neurochemical consequences of acute stress in rodents. In these preclinical models, LY354740 does not produce the side-effects (e.g. sedation) that are associated with other anxiolytic agents such as benzodiazepines. Early clinical results with LY354740 have demonstrated safety and efficacy in a human anxiety model (panic provocation induced by CO2 challenge). Collectively, these data indicate mGlu2/3 receptor agonists such as LY354740 represent a promising new approach for treatment of anxiety and stress-related disorders in humans.     

Part-list reexposure and release of retrieval inhibition

In list-method directed forgetting, reexposure to forgotten List 1 items has been shown to reduce directed forgetting. proposed that reexposure to a few List 1 items only during a direct test of memory reinstates the entire List 1 episode. In the present experiments, part-list reexposure in the context of indirect as well as direct memory tests reduced directed forgetting. Directed forgetting was reduced when 50% or more of the items were reexposed, and was intact when only 25% were reexposed. Furthermore, part-list reexposure appeared to reinstate only reexposed items-not the entire List 1 episode.
