Attachment style, ethnicity and help-seeking attitudes among adolescent pupils

The present study set out to explore influences on help-seeking attitudes among adolescents. The roles of attachment style, ethnicity and symptomatology were examined, as previous research (predominantly from outside the UK) has shown they have an influence on help-seeking. A self-report questionnaire survey of help-seeking attitudes was carried out among 112 Asian, black and white UK pupils (age 15 years). Teachers were identified as the most frequently used source of previous professional help. Greater intentions to seek help were associated with being female, having a secure attachment style and having had previous experience of obtaining professional psychological help, but ethnicity and level of emotional and behavioural difficulties did not predict. Results are discussed in terms of implications for enhancing adolescent help-seeking.     

The impact of death qualification, belief in a just world, legal authoritarianism, and locus of control on venirepersons' evaluations of aggravating and mitigating circumstances in capital trials

The purpose of this study was to investigate the impact of death qualification, belief in a just world (BJW), legal authoritarianism (RLAQ), and locus of control (LOC) on venirepersons' evaluations of aggravating and mitigating circumstances in capital trials. 212 venirepersons from the 12th Judicial Circuit in Bradenton, FL, completed a booklet that contained the following: one question that measured their attitudes toward the death penalty; one question that categorized their death-qualification status; the BJW, LOC, and RLAQ scales; a summary of the guilt and penalty phases of a capital case; a 26-item measure that required participants to evaluate aggravators, nonstatutory mitigators, and statutory mitigators on a 6-point Likert scale; sentence preference; and standard demographic questions. Results indicated that death-qualified venirepersons were more likely to demonstrate higher endorsements of aggravating factors and lower endorsements of both nonstatutory and statutory mitigating factors. Death-qualified participants were also more likely to have a high belief in a just world, espouse legal authoritarian beliefs, and exhibit an internal locus of control. Findings also suggested that venirepersons with a low belief in a just world and an external locus of control demonstrated higher endorsements of statutory mitigators. Participants with legal authoritarian beliefs revealed higher endorsements of aggravators and lower endorsements of nonstatutory mitigators. Legal implications and applications are discussed.     

Opposing effects on muscarinic acetylcholine receptors in the piriform cortex of odor-trained rats

We combined pharmacological studies and electrophysiological recordings to investigate modifications in muscarinic acetylcholine (ACh) receptors (mAChR) in the rat olfactory (piriform) cortex, following odor-discrimination rule learning. Rats were trained to discriminate between positive and negative cues in pairs of odors, until they reached a phase of high capability to learn unfamiliar odors, using the same paradigm (“rule learning”). It has been reported that at 1–3 d after the acquisition of odor-discrimination rule learning, pyramidal neurons in the rat piriform cortex show enhanced excitability, due to a reduction in the spike-activated potassium current I_AHP, which is modulated by ACh. Further, ACh and its analog, carbachol (CCh), lost the ability to reduce the I_AHP in neurons from trained rats. Here we show that the reduced sensitivity to CCh in the piriform cortex results from a decrease in the number of mAChRs, as well as a reduction in the affinity of the receptors to CCh. Also, it has been reported that 3–8 d after the acquisition of odor-discrimination rule learning, synaptic transmission in the piriform cortex is enhanced, and paired-pulse facilitation (PPF) in response to twin stimulations is reduced. Here, intracellular recordings from pyramidal neurons show that CCh increases PPF in the piriform cortex from odor-trained rats more than in control rats, suggesting enhanced effect of ACh in inhibiting presynaptic glutamate release after odor training.     

The effect of the validity of co‐occurrence on automatic and deliberate evaluations

Co‐occurrence of an object and affective stimuli does not always mean that the object and the stimuli are the same valence (e.g., false accusations that Richard is a crook). Contemporary theory posits that information about the (in)validity of co‐occurrence has stronger influence on deliberate than automatic evaluation. However, available evidence supports that hypothesis only when the (in)validity information is delayed. Further, the existing evidence is open to alternative methodological accounts. In six high‐powered experiments (total N = 1750), we modified previous procedures to minimize alternative explanations and examine whether delayed (in)validity information has a discrepant effect on automatic versus deliberate evaluation. Casting doubt on the generality of the hypothesis, we found more sensitivity of deliberate than automatic evaluation to delayed validity information only when automatic evaluation was measured with the Implicit Association Test and not with the evaluative priming task or the affective misattribution procedure.     

Consumer Preference Programs for Individuals Who Are Homeless and Have Psychiatric Disabilities: A Drop-In Center and a Supported Housing Program

We illustrate Fairweather's approach to Experimental Social Innovation and Dissemination with two experimental studies of programs to reduce homelessness for 168 and 225 people with mental illness and often substance abuse. Literally homeless participants were randomly assigned to programs that emphasized consumer choice or to the usual continuum of care, in which housing and services are contingent on sobriety and progress in treatment. A drop-in center that eliminated barriers to access to services was more successful than control programs in reducing homelessness, but after 24 months only 38% of participants had moved to community housing. A subsequent apartment program, in which individuals in the experimental condition moved to subsidized apartments directly from the street, with services under their control, had 79% in stable housing (compared to 27% in the control group) at the end of 6 months. Groups in this study did not differ on substance abuse or psychosocial outcomes.     

What makes people happy? Decoupling the experiential-material continuum

Extant literature suggests that consumers derive more happiness from experiences (e.g., vacations) than from material possessions (e.g., furniture). However, this literature typically pits material against experiential consumption, treating them as a single bipolar construct of their relative dominance: more material or more experiential. This focus on relative dominance leaves unanswered questions regarding how different levels of material and experiential qualities each contribute to happiness. Four preregistered studies (N = 3,288), using hundreds of product categories, measured levels of material and experiential qualities using two unipolar items. These studies investigate recalled, evoked, and anticipated happiness. Results show a more nuanced view of the experiential advantage that is critical for future research and consumer theory: material and experiential qualities both have positive relationships with happiness. Further, there is no inherent trade-off between experiential and material qualities: consumers can enjoy consumption that is high on both (e.g., swimming pools and home improvements).     

Absolutely relative or relatively absolute: violations of value invariance in human decision making

Making decisions based on relative rather than absolute information processing is tied to choice optimality via the accumulation of evidence differences and to canonical neural processing via accumulation of evidence ratios. These theoretical frameworks predict invariance of decision latencies to absolute intensities that maintain differences and ratios, respectively. While information about the absolute values of the choice alternatives is not necessary for choosing the best alternative, it may nevertheless hold valuable information about the context of the decision. To test the sensitivity of human decision making to absolute values, we manipulated the intensities of brightness stimuli pairs while preserving either their differences or their ratios. Although asked to choose the brighter alternative relative to the other, participants responded faster to higher absolute values. Thus, our results provide empirical evidence for human sensitivity to task irrelevant absolute values indicating a hard-wired mechanism that precedes executive control. Computational investigations of several modelling architectures reveal two alternative accounts for this phenomenon, which combine absolute and relative processing. One account involves accumulation of differences with activation dependent processing noise and the other emerges from accumulation of absolute values subject to the temporal dynamics of lateral inhibition. The potential adaptive role of such choice mechanisms is discussed.
