Abstract reasoning and the interpretation of basic conditionals

Studies examining the interpretation that is given to if–then statementstypically use what are referred to as basic conditionals, which give contextless relations between two unrelated concrete terms (If the ball is blue, then the shape is square). However, there is some evidence that basic conditionals require a more abstract form of representation. In order to examine this, we presented participants with truth-table tasks involving either basic conditionals or conditionals referring to imaginary categories (If it is a bori, then it has red wings), and standard conditional inference tasks with abstract and familiar premises. As expected, fewer typical defective conditional interpretations were given to basic conditionals. In addition, partial correlations showed a unique relationship between the interpretation of basic conditionals and abstract inferential reasoning. Results suggest that people process basic conditionals as a form of abstract reasoning, and that the interpretation of conditionals must consider the semantic context.     

Health disparities between binary and non binary trans people: A community-driven survey

Abstract

Background: Genderqueer and nonbinary () people have remained largely invisible in health research. Previous research shows worse outcomes on health indicators for trans people when compared with cisgender controls, but the differences between binary trans and GQNB individuals are inconclusive.

Aims: To compare overall health and well-being of GQNB people with controls of trans men and trans women, taking into account the impact of the additive effect of their socio-economic position, as well as their current need for gender affirming medical interventions.

Methods: A community-driven survey was conducted in 2016 in five countries (Georgia, Poland, Serbia, Spain, and Sweden). Self-reported health and general well-being were analysed for differences between binary trans and GQNB respondents. The effects of multiple control variables (age, economic situation, educational level, belonging to an ethnic, religious, sexual or ability minority group, sex assigned at birth) as well as the current need for gender affirming medical interventions were controlled for.

Results: The sample consisted of 853 respondents aged 16 and older, with 254 trans women (29.8%), 369 trans men (43.2%), and 230 GQNB people (26%). GQNB respondents showed significantly worse self-reported health and worse general well-being in comparison to binary trans respondents. Additional negative impacts of having a lower educational level, having more economic stress, and belonging to a disability minority group were found. Being in need of gender affirming medical interventions contributed significantly to worse self-reported health, whereas being younger contributed to worse general well-being.

Discussion: In understanding health disparities between binary trans and GQNB people, it is necessary to take into account the additive effect of multiple socio-economic positions, and the current need for gender affirming medical interventions. The high proportion of GQNB respondents who report worse health outcomes highlights the need for policy makers and health-care providers in creating nonbinary-inclusive environments.     

Putting a negative spin on it: Using a fidget spinner can impair memory for a video lecture

Fidget spinners have experienced a rapid rise in popularity, at least partially because they are marketed as attentional aides with the potential to enhance student learning. In the current study, college-aged students watched educational videos while either using a fidget spinner or not. Using a fidget spinner was associated with increased reports of attentional lapses, diminished judgments of learning, and impaired performance on a memory test for the material covered in the video. The adverse effect on learning was observed regardless of whether the use of fidget spinners was manipulated between-subjects (Experiment 1) or within-subjects (Experiment 2), and was observed even when the sample and analysis were limited to participants who came into the study with neutral or positive views on the use of fidget spinners. These results suggest that if fidget spinners are beneficial for learning, such benefits are relatively limited or at least do not extend to the conditions present in the current study.     

Changes in reality monitoring and episodic memory in early childhood

The purposes of this research were to examine the developmental relation between reality monitoring and episodic memory, to link reality monitoring to autobiographical memory by using extended naturalistic events, and to examine prefrontal functioning as a potential contributor to development in reality monitoring and episodic memory. In Experiment 1, 4-year-olds were worse than 6- or 8-year-olds at reality monitoring after a week delay, despite the fact that they remembered more about real than imagined events and remembered different aspects of each. In Experiments 2 and 3, reality monitoring and episodic memory were evaluated for 4- and 6-year-olds immediately after the events occurred and, in Experiment 3, again after a week delay. Reality monitoring was at higher levels for both age groups, but age differences remained. These data suggest that preschoolers' difficulties with reality monitoring result from a combination of episodic memory deficits and strategic differences. In addition, correlation analyses more directly linked preschoolers' reality monitoring to episodic memory and supported the hypothesis that episodic memory development is related to prefrontal functioning.     

Sensation seeking, aggression, and reckless behavior in high school students, college students, and adults

Replicating work of Arnett, males reported more frequent Reckless Behavior than females, and 27 high school and 48 college students did not differ in scores on Sensation Seeking or Aggression. As anticipated by Arnett, the 35 adults had significantly lower Sensation Seeking and Aggression scores than the two younger groups and less Reckless Behavior as well. In contrast to Arnett, Reckless Behavior did not rise for college students, and Sensation Seeking, but not Aggression, correlated with Reckless Behavior in all samples.     

Dynamics of verbal interaction between interviewer and child in interviews with alleged victims of child sexual abuse

A number (n = 27) of investigative interviews with children were analyzed with a view to explore the verbal dynamics between interviewer and child. Different types of interviewer utterances and child responses were defined, and the interrelationships between these were explored. The effectiveness of different interviewer utterances in eliciting information from children as well as the type of utterance the interviewer used to follow up an informative answer by the child were investigated. Option-posing and suggestive utterances made up for more than 50% of interviewer utterances, the proportion of invitations being only 2%. Invitations and directive utterances were associated with an increase in informative responses by the child, the adverse being true for option-posing and suggestive utterances. Interestingly, even after the child had provided an informative answer, interviewers continued to rely on focused and leading interviewing methods--in spite of a slight improvement in interviewing behavior.     

Reasoning with premises that are not empirically true: evidence for the role of inhibition and retrieval

Two studies examined conditional reasoning with false premises. In Study 1, 12- and 16-year-old adolescents made "if-then" inferences after producing an alternative antecedent for the major premise. Older participants made more errors on the simple modus ponens inference than did younger ones. Reasoning with a false premise reduced this effect. Study 2 examined the relation between performance on a negative priming task (S. P. Tipper, 1985) and reasoning with contrary-to-fact premises in 9- and 11-year-olds. Overall, there was a correlation between the relative effect of negative priming on reaction times and the number of knowledge-based responses to the reasoning problems. The results of these studies are consistent with the idea that reasoning with premises that are not true requires an interaction between information retrieval and inhibition.     

Midazolam amnesia and retrieval from semantic memory: Developing methods to test theories of implicit memory

Studies of organic anterograde amnesia have been central to the development of theories of implicit memory. Pharmacological amnesia provides an additional method for exploring implicit memory, allowing for the experimental manipulation of amnesia and the testing of more participants. A significant concern with pharmacological amnesia is whether its cognitive effects are specific to explicit memory. The current research examines the effects of the benzodiazepine, midazolam, on retrieval from semantic memory and encoding in explicit memory. We focus on midazolam because it holds significant advantages over other benzodiazepines in inducing pharmacological amnesia and prior research suggests it may be useful for testing theories of implicit memory. Our results demonstrate that midazolam does not impair accuracy of retrieval from semantic categories, even when it produces anterograde amnesia for retrieved category items on a later recall test. These results suggest ways midazolam can be used to help test theories of implicit memory.
