Does mediator use contribute to the spacing effect for cued recall? Critical tests of the mediator hypothesis

When study is spaced across sessions (versus massed within a single session), final performance is greater after spacing. This spacing effect may have multiple causes, and according to the mediator hypothesis, part of the effect can be explained by the use of mediator-based strategies. This hypothesis proposes that when study is spaced across sessions, rather than massed within a session, more mediators will be generated that are longer lasting and hence more mediators will be available to support criterion recall. In two experiments, participants were randomly assigned to study paired associates using either a spaced or massed schedule. They reported strategy use for each item during study trials and during the final test. Consistent with the mediator hypothesis, participants who had spaced (as compared to massed) practice reported using more mediators on the final test. This use of effective mediators also statistically accounted for some – but not all of – the spacing effect on final performance.     

Équivalence de la version en français pour le Canada et de la version originale états-unienne de l’Adult Self-Report

The aim of the present study was to evaluate the equivalence of the French-Canadian version of the Adult Self-Report (ASR; Achenbach & Rescorla, 2003) to its original English (USA) version. Both the original English version and the newly translated French-Canadian version were administered to 251 bilingual students from four Canadian provinces (Manitoba, New-Brunswick, Ontario, and Quebec), with a one to two weeks interval. Correlations varying from 0.72 to 0.87 indicated a high degree of correspondence between the scales of the two versions. Cohen's d calculated using Morris and DeShon's (2002) formula for within-subjects designs indicate that differences between mean scores varied from near-zero (d = 0.01) to small (d = 0.19), and suggest that they are not clinically significant. Ordinal alpha coefficients for the scales of the French-Canadian version varied from 0.66 to 0.96 but are inferior to those of the English version in seven of the eleven scales. Globally, results indicate that the equivalence of the French-Canadian version to the original English version of the ASR is sufficient to recommend its use.     

Object-Tool-Actor Interaction: Object Information Drives Intended Action

Tool use is typically explored via actor-tool interactions. However, the target-object (that which is being acted on) may influence perceived action possibilities and thereby guide action. Three different tool-target-object pairings were tested (Experiment 1). The hammering action demonstrated the greatest sensitivity and therefore subsequently used to further investigate target-object pairings. The hammer was removed as an option and instructions were provided using pictorial (Experiment 2), written (Experiment 3), and both pictorial and written formats (Experiment 4). The designed tool is chosen when available (Experiment 1) and when removed as a choice (i.e., the hammer), participants perform the same action associated with the designed tool (i.e., hammering) regardless of instruction method (Experiments 2, 3, and 4).     

The Association Between Psychological Well-Being and Problematic Use of Internet Communicative Services Among Young People

Previous studies on problematic Internet use have focused almost exclusively on the fact that presence of negative functioning, such as social anxiety, depressive symptoms, or loneliness, represents a risk factor for unhealthy use of the web. For this reason the aim of the present study was to investigate the association between psychological well-being dimensions and problematic use of Internet communicative services. In the current study 495 undergraduate students were recruited. The Italian adaptations of the Psychological Well-being Scales and the Generalized Problematic Internet Use Scale 2 (GPIUS2) were used to assess psychological well-being dimensions and generalized problematic Internet use, respectively. Psychological well-being dimensions explained a significant portion of variance for the GPIUS2 total score levels, after controlling for sex, age, and occupational status. The levels of Autonomy, Environmental Mastery, and Positive Relations with Others acted as significant negative predictors of the tendency to use the web for regulating negative feelings, compulsive use of the web, and the negative outcomes that can arise as a result. The overall findings of the present study provide preliminary evidence that low psychological well-being is associated with problematic use of Internet communicative services.     

Perceptions of Private Market Landlords Who Rent to Tenants of a Housing First Program

The rental of housing units by landlords to participants in Housing First (HF) programs is critical to the success of these programs. Therefore, it is important to understand the experiences of landlords with having these individuals as tenants. The paper presents findings of qualitative interviews with 23 landlords who rented to tenants from a HF program located in a small city and adjoining rural area in eastern Canada and in which approximately 75 % of tenants had been housed for at least six consecutive months at 2 years in the program. Findings showed that landlords are motivated to rent to HF tenants for financial and pro‐social reasons. They reported holding a range of positive, neutral, and negative perceptions of these tenants. They identified problems encountered with some HF tenants that included disruptive visitors, conflict with other tenants, constant presence in their apartments, and poor upkeep of units. On the other hand, landlords perceived HF tenants as being mostly good tenants who are similar to their other tenants. Implications for practice in the context of HF programs are discussed.     

Drug Use Among Immigrant and Non‐immigrant Adolescents: Immigrant Paradox,Family and Peer Influences

The present study compared immigrant and Italian native adolescents with regard to drug use. Additionally, we analysed the role of family and peer risk and protective factors for drug use. Participants included 2533 Italian native and immigrant adolescents (mean age = 17.19, SD = 1.6; 66.7% male). Results showed that immigrant adolescents reported lower levels of marijuana and pharmaceutical drug abuse than non‐immigrant adolescents. These results confirm the so‐called immigrant paradox phenomenon: the counterintuitive finding that although immigrants often live under challenging conditions and reported lower economic affluence compared with nationals, some health outcomes have not always corresponded to their relative disadvantage. Immigrant adolescents also reported higher level of parental control and lower levels of affiliation with deviant peers, but lower levels of child disclosure, parental solicitation and parental knowledge. Socio‐economic status and parental monitoring showed equivalent effects on drug use for immigrant and non‐immigrant adolescents. Results have implications for preventive interventions for immigrant adolescents and families, including the need to develop programmes that leverage the benefits of the immigrant paradox for immigrant communities. Future research should analyse the processes that lead to lower levels of drug use in immigrant adolescents and investigate the influence of friendship networks on immigrant adolescent drug use behaviour.

Are some video games associated with more life interference and psychopathology than others? Comparing massively multiplayer online role‐playing games with other forms of video game

Massively multiplayer online role‐playing games (MMORPGs) are a type of video game that is considered to have particular potential to be associated with life interference and psychopathology when played frequently and intensively. This study sought to compare players of MMORPGs with players of other types of video game in terms of problematic use, life interference, and levels of psychopathology. An international sample of 1,945 video game players completed a series of questionnaires online. While MMORPG players reported increased rates of problematic use and life interference compared with non‐MMORPG players, there were no differences in levels of psychopathology. Differences between MMORPG players and non‐MMORPG players appeared to be associated with the increased amounts of time that MMORPG players played for: The amount of time spent playing appeared to mediate the relationships between type of game played and each of the problematic use and life interference variables. The implications of these findings are discussed.     

A psychoanalytically informed hospitalization‐based treatment of personality disorders

This study presents a model of psychic change in personality disorders focusing on three dimensions: felt safety, mentalization and self‐object relations. Based upon this model a hospitalization‐based therapy program was created. Four scales to measure these three dimensions on the Object Relation Interview are discussed: the Felt Safety Scale, the Reflective Functioning Scale and the Bion Grid Scale and the Differentiation‐Relatedness Scale. A naturalistic symptom outcome study of the program showed a large effect on both symptoms and personality functioning. Furthermore, trajectory based on pre‐treatment patient characteristics (i.e., anaclitic versus introjective personality styles). Importantly, we also found a relation between symptomatic and personality change and change in felt safety and object relations. At 5‐year follow‐up, patients showed sustained improvement in symptomatic distress and further improvement in terms of personality and interpersonal functioning.
