Assessing learning processes with the gain-loss model

Within the framework of knowledge space theory, a probabilistic skill multimap model for assessing learning processes is proposed. The learning process of a student is modeled as a function of the interaction between his competence state and the effect of a learning object on specific skills. Model parameters are initial probabilities of the skills, effects of learning objects on gaining and losing the skills, careless error, and lucky guess probabilities of the problems. A simulation study assessed model identifiability and goodness-of-recovery under several conditions. Practical implications of using the model are discussed, and the MATLAB code for simulating, estimating and testing it is available in the Psychonomic Society supplemental archive.     

“Everybody feels a broken bone,but only we can feel a broken heart”: Group membership influences the perception of targets' suffering

There is surmounting evidence in the literature demonstrating that social pain (e.g. rejection, humiliation, and isolation) and physical pain (e.g. injury or assault) overlap in personal experiences. The present investigation focuses on second‐hand perceptions of social and physical pain. We argue that judgments of others' pain may vary as a function of group membership. By integrating research on intergroup bias in pain judgment with intergroup attributions of humanity, we predicted that observers tend to underestimate social pain more than physical pain in out‐groups compared with in‐groups. Across two studies that considered different scenarios, we found that Italian participants attributed less severe social pain when considering an out‐group (Chinese and Ecuadorian) than an in‐group member. No such effect was found for physical pain. Overall, the current work suggests an additional way through which people preserve a privileged human status to in‐group members while denying out‐group members' humanness.

Social Representations,Individual and Collective Mind: A Study of Wundt,Cattaneo and Moscovici

The paper presents a discussion on the role of Social Representations in the articulation between individual and collective dimensions of mental activity. An analysis of some concepts in the works of Wundt and Cattaneo is the starting point for a discussion of the relationship between individual processes, practices, artifacts, symbolic systems and functions of Social Representations in the development of culture and individuals. In this perspective, Social Representations could be considered a space of negotiation of the meaning. The relationship between Social Representations, symbolic systems, practices and sense making involves the elaboration of the tension between continuity and innovation, which is developed through communication and practice along time in the interaction between individual and collective minds.     

Latino and Latina Adolescents' Help‐seeking Behaviors and Attitudes Regarding Suicide Compared to Peers with Recent Suicidal Ideation

Although Latinas have consistently reported higher rates of suicidal behavior for the past 20 years (CDC, 1996), there is a dearth of information regarding their help‐seeking attitudes and behaviors when dealing with distress and suicide. Associations between adolescents' ideation and help‐seeking from adults were different for non‐Hispanic Whites and Latinos from 14 high schools (N = 4,983). Among females, ideators and Latinas reported lower levels of help‐seeking attitudes than nonideators and non‐Hispanic Whites. Males showed interaction effects of ideation by race/ethnicity on help‐seeking. Within sex by race/ethnicity, differences showed that while non‐Hispanic White students reported consistent differences between suicidal ideation and no reported suicidal ideation, Latinos were more similar between these groups, particularly with having support from friends and family to seek help from adults. Research should clarify how culture contributes to decreased help‐seeking norms among those with suicidal ideation.     

The larger the cause,the larger the effect: evidence of speed judgment biases in causal scenarios

ABSTRACT

When two motions appear to be causally related, the spatiotemporal features of motions are sometimes distorted in order to increase the consistency with causal impressions. Here, in four experiments, we tested if varying the speed of an object A could affect the judged speed of an object B that appeared to be causally related to A. Participants were presented with classic launching stimuli (Experiment 1), a variant of launching stimuli in which A could move with uniformly accelerated or decelerated motion (Experiment 2), non-launching stimuli that elicited a causal impression (Experiment 3), and stimuli showing a three-object launching event (Experiment 4). Main results showed that the judged speed of B was systematically biased towards the speed of A, and moreover that the judged speed of B depended on the average speed of A, rather than on the speed of A at the moment of collision as it would be predicted by Newtonian mechanics. The results are consistent with the hypothesis that internal representations of causal events based on property transmission (for instance, impetus) can affect judgments of the low-level properties of causal scenarios.     

Along the border: affective promotion or inhibition of conduct in urban spaces / A lo largo de la frontera: promoción o inhibición afectiva de la conducta en los espacios urbanos

Abstract

The concepts of borders, tensegrity and goal-oriented meaningful conduct are used to study the conditions in which affects and conducts can (or cannot) emerge in urban spaces. We assume psychological phenomena are liminal and emerge in the border zones between different individual and collective states. The main focus of the study is the process of affective meaning-making that takes place at specific locations (the border zones) in urban living. Through an example of autoethnography, we try to understand how the symbolic space is used in everyday life to produce, maintain and demolish signs that self-regulate and hetero-regulate complex atmospheres, affects and conducts.     

Acute Alcohol Co‐Ingestion and Hospital‐Treated Deliberate Self‐Poisoning: Is There an Effect on Subsequent Self‐Harm?

The aim of this study was to determine the relationship between alcohol co‐ingestion in an index deliberate self‐poisoning (DSP) episode with repeated DSP and subsequent suicide. A retrospective cohort study was conducted involving 5,669 consecutive index presentations to a toxicology service following DSP between January 1, 1996, and October 31, 2010. Records were probabilistically matched to National Coronial Information System data to identify subsequent suicide. Index DSPs were categorized on co‐ingestion of alcohol, and primary outcomes analyzed were repetition of any DSP, rates of repeated DSP, time to first repeat DSP, and subsequent suicide. Co‐ingestion of alcohol occurred in 35.9% of index admissions. There was no difference between those who co‐ingested alcohol (ALC+) and those who did not co‐ingest alcohol (ALC?) in terms of proportion of repeat DSP, number of DSP events, or time to first repeat DSP event. Forty‐one (1.0%) cases were probabilistically matched to a suicide death; there was no difference in the proportion of suicide between ALC+ and ALC? at 1 or 3 years. There was no significant relationship between the co‐ingestion of alcohol in an index DSP and subsequent repeated DSP or suicide. Clinically, this highlights the importance of mental health assessment of patients that present after DSP, irrespective of alcohol co‐ingestion at the time of event.
