Public self‐consciousness disposition effect on reactions to waiting in line

In this paper, we investigate how high public self‐conscious subjects may display specific reactions while waiting in line with strangers at a movie theatre. Results suggest that, when compared with low public subjects, high public self‐conscious subjects will have an attentional focus directed toward time, will attribute more control to service managers for the cause of the wait and will evaluate the service more negatively. Results concerning relationships between attribution of control, behavioural intentions and service evaluation support those of previous studies and are both directly and indirectly moderated by the public self‐consciousness disposition. This research opens the way to conducting future studies attempting to link other personality dispositions with consumer behaviour in the services domain.

The Transformation of Girls to Women: Finding Voice and Developing Strategies for Liberation

The theme of silence is one of the most pervasive themes in the study of girls and women across cultures. The authors examine emotional, physical, educational, and behavioral losses that occur for adolescent girls. Results of landmark research studies and the implications for practitioners also are discussed. El tema del silencio es uno de los temas más penetrantes en el estudio de jovencitas y mujeres a través de las culturas. Los autores examinan las pérdidas emocionales, físicas, educativas y de comportamiento que ocurren para las jovencitas adolescentes. Los resultados de estudios culminantes y las implicaciones para consejeros se discuten.     

Gender congruence and body satisfaction in nonbinary transgender people: A case control study

Abstract

Background: Binary transgender people access gender affirming medical interventions to alleviate gender incongruence and increase body satisfaction. Despite the increase in nonbinary transgender people, this population are less likely to access transgender health services compared to binary transgender people. No research has yet understood why by exploring levels of gender congruence and body satisfaction in nonbinary transgender people.

Objective: The aim of this study was to compare levels of gender congruence and body satisfaction in nonbinary transgender people to controls [binary transgender people and cisgender (nontrans) people].

Method: In total, 526 people from a community sample in the UK took part in the study (97 nonbinary, 91 binary, and 338 cisgender identifying people). Participants were asked to complete an online survey about gender congruence and body satisfaction.

Results: There were differences in gender congruence and body satisfaction between nonbinary and binary transgender people. On sex-specific parts of the body (i.e., chest, genitalia, and secondary sex characteristics), nonbinary transgender people reported significantly higher levels of gender and body satisfaction compared to binary transgender people. However, there was no difference in congruence and satisfaction with social gender role between the two transgender groups (nonbinary and binary). Cisgender people reported significantly higher levels of gender congruence and body satisfaction compared to transgender people (nonbinary and binary).

Conclusions: There are differences in gender congruence and body satisfaction between nonbinary and binary transgender people. Nonbinary individuals may be less likely to access transgender health services due to experiencing less gender incongruence and more body satisfaction compared to binary transgender people. Transgender health services need to be more inclusive of nonbinary transgender people and their support and treatment needs, which may differ from those who identify within the binary gender system.     

Strategies in subtraction problem solving in children

The aim of this study was to investigate the strategies used by third graders in solving the 81 elementary subtractions that are the inverses of the one-digit additions with addends from 1 to 9 recently studied by Barrouillet and Lépine. Although the pattern of relationship between individual differences in working memory, on the one hand, and strategy choices and response times, on the other, was the same in both operations, subtraction and addition differed in two important ways. First, the strategy of direct retrieval was less frequent in subtraction than in addition and was even less frequent in subtraction solving than the recourse to the corresponding additive fact. Second, contrary to addition, the retrieval of subtractive answers is confined to some peculiar problems involving 1 as the subtrahend or the remainder. The implications of these findings for developmental theories of mental arithmetic are discussed.     

Postscript: A good psychological theory of reasoning must predict behavior and explain the data

In their stimulating comment on Barrouillet, Gauffroy, and Lecas Oberauer and Oaksford argued that we gave no rationale for the assumption that the mental models of false-antecedent cases have a different epistemic status from the p q model and that no new computational level account of the conditional was provided to justify this move. The resulting lack of coherent principles would undermine the heuristic power of the mental model theory and lead to unacceptable consequences. Though our theory probably presents many weaknesses, it is false to assume that we did not give any rationale for the truth value gap of conditionals. Our proposal elaborates the distinction between initial and fleshed-out models that is at the core of the theory from its very beginning (Johnson-Laird & Byrne, 1991), and assumes that people consider those cases that match the initial model as making the conditional true whereas the cases that match the models added through fleshing out are judged as leaving its truth value indeterminate.

Mental models and the suppositional account of conditionals

The mental model theory of conditional reasoning presented by P. N. Johnson-Laird and R. M. J. Byrne (2002) has recently been the subject of criticisms (e.g., J. St. B. T. Evans, D. E. Over, & S. J. Handley, 2005). The authors argue that the theoretical conflict can be resolved by differentiating 2 kinds of reasoning, reasoning about possibilities given the truth of assertions and reasoning about the truth of assertions given possibilities. The standard mental model theory accounts for the former kind of reasoning but does not adequately account for the latter, contrary to the suppositional approach favored by J. St. B. T. Evans et al. (2005). The authors thus propose a modified mental model theory of conditionals that reconciles the 2 theoretical approaches. It is demonstrated that this theory is able to explain the key findings that have been opposed to the standard theory by J. St. B. T. Evans et al. and makes new predictions that are empirically verified.     

The NO-cGMP-PKG signaling pathway regulates synaptic plasticity and fear memory consolidation in the lateral amygdala via activation of ERK/MAP kinase

Recent studies have shown that nitric oxide (NO) signaling plays a crucial role in memory consolidation of Pavlovian fear conditioning and in synaptic plasticity in the lateral amygdala (LA). In the present experiments, we examined the role of the cGMP-dependent protein kinase (PKG), a downstream effector of NO, in fear memory consolidation and long-term potentiation (LTP) at thalamic and cortical input pathways to the LA. In behavioral experiments, rats given intra-LA infusions of either the PKG inhibitor Rp-8-Br-PET-cGMPS or the PKG activator 8-Br-cGMP exhibited dose-dependent impairments or enhancements of fear memory consolidation, respectively. In slice electrophysiology experiments, bath application of Rp-8-Br-PET-cGMPS or the guanylyl cyclase inhibitor LY83583 impaired LTP at thalamic, but not cortical inputs to the LA, while bath application of 8-Br-cGMP or the guanylyl cyclase activator YC-1 resulted in enhanced LTP at thalamic inputs to the LA. Interestingly, YC-1-induced enhancement of LTP in the LA was reversed by concurrent application of the MEK inhibitor U0126, suggesting that the NO-cGMP-PKG signaling pathway may promote synaptic plasticity and fear memory formation in the LA, in part by activating the ERK/MAPK signaling cascade. As a test of this hypothesis, we next showed that rats given intra-LA infusion of the PKG inhibitor Rp-8-Br-PET-cGMPS or the PKG activator 8-Br-cGMP exhibit impaired or enhanced activation, respectively, of ERK/MAPK in the LA after fear conditioning. Collectively, our findings suggest that an NO-cGMP-PKG-dependent form of synaptic plasticity at thalamic input synapses to the LA may underlie memory consolidation of Pavlovian fear conditioning, in part, via activation of the ERK/MAPK signaling cascade.
