Toward a Unified Framework for the Study of Between-Person and Within-Person Structures: Building a Bridge Between Two Research Paradigms

The vast majority of empirical research in the behavioral sciences is based on the analysis of between-person variation. In contrast, much of applied psychology is concerned with the analysis of variation within individuals. Furthermore, the mechanisms specified by psychological theories generally operate within, rather than across, individuals. This disconnect between research practice, applied demands, and psychological theories constitutes a major threat to the conceptual integrity of the field. Following groundbreaking earlier work, we propose a conceptual framework that distinguishes within-person (WP) and between-person (BP) sources of variation in psychological constructs. By simultaneously considering both sources of variation, it is shown how to identify possible reasons for nonequivalence of BP and WP structures as well as establishing areas of convergence. For this purpose, we first introduce the concept of conditional equivalence as a way to study partial structural equivalence of BP and WP structures in the presence of unconditional nonequivalence. Second, we demonstrate the construction of likelihood planes to explore the causes of structural nonequivalence. Third, we examine 4 common causes for unconditional nonequivalence—autoregression, subgroup differences, linear trends, and cyclic trends—and demonstrate how to account for them. Fourth, we provide an empirical example on BP and WP differences in attentiveness.     

Disentangling Context Availability and Concreteness in Lexical Decision and W ord Translation

This study examines contrasting predictions of the dual coding theory and the context availability hypothesis regarding concreteness effects in monolingual and bilingual lexical processing. In three experiments, concreteness was controlled for or confounded with rated context availability. In the first experiment, bilingual subjects performed lexical decision in their native language (Dutch, L1). In the second experiment, lexical decision performance of bilinguals in their second language (English, L2) was examined. In the third experiment, bilinguals translated words 'forwards' (from L1 to L2) or 'backwards' (from L2 to L1). Both monolingual and bilingual tasks showed a concreteness effect when concreteness was confounded with context availability. However, concreteness effects disappeared when abstract and concrete words were matched on context availability, and even occasionally reversed. Implications of these results for theories that account for concreteness effects, particulary in bilingual processing, are discussed.     

Apes are intuitive statisticians

Inductive learning and reasoning, as we use it both in everyday life and in science, is characterized by flexible inferences based on statistical information: inferences from populations to samples and vice versa. Many forms of such statistical reasoning have been found to develop late in human ontogeny, depending on formal education and language, and to be fragile even in adults. New revolutionary research, however, suggests that even preverbal human infants make use of intuitive statistics. Here, we conducted the first investigation of such intuitive statistical reasoning with non-human primates. In a series of 7 experiments, Bonobos, Chimpanzees, Gorillas and Orangutans drew flexible statistical inferences from populations to samples. These inferences, furthermore, were truly based on statistical information regarding the relative frequency distributions in a population, and not on absolute frequencies. Intuitive statistics in its most basic form is thus an evolutionarily more ancient rather than a uniquely human capacity.     

Childhood Predictors of Adulthood Antisocial Personality Disorder Symptomatology

The present study aimed to examine relationships between antisocial personality disorder (APD) symptoms in adulthood and retrospective reports of childhood maltreatment, parental bonding, and teasing, and while controlling for symptoms of depression and anxiety. Four hundred eleven non‐clinical participants (99 males, 312 females), aged 18–65 years, recruited from an Australian university and the general public, completed the questionnaire package. Findings indicated significant associations between childhood maltreatment, parental bonding, teasing, depression, and anxiety, and levels of APD symptomatology. Hierarchical regression analysis revealed that physical abuse, physical neglect, teasing, and level of father care made the largest unique contributions to the prediction of APD scores after statistically controlling for comorbid depression and anxiety. Analysis of variance revealed higher levels of APD symptoms were reported by males and younger participants. This research contributes importantly to our understanding of factors influencing APD symptomatology, with clinical and early intervention implications.     

Improving Experience in Personal Social Systems through Family Constellation Seminars: Results of a Randomized Controlled Trial

This study examined the efficacy of family constellation seminars (FCSs) on individuals' experience in their personal social systems, especially the experience of belonging, autonomy, accord, and confidence. We conducted a single‐blind, stratified and balanced, randomized controlled trial. Participants were 208 adults (M = 48 years, SD = 10, 79% women) who were randomly allocated either to the intervention group (3‐day FCSs; 64 active participants, 40 observing participants) or to the wait‐list group (64 active participants, 40 observing participants). Change was measured short‐term (2‐week and 4‐month follow‐up) using the Experience In Social Systems Questionnaire, personal domain (EXIS.pers). EXIS.pers is a new outcome measure being applied for the first time in evaluation research. In addition, we used interpersonal scales derived from established measures (Outcome Questionnaire, OQ‐45; Tool for the Evaluation of the Psychotherapeutic Progress, FEP). The average person in the intervention group showed improved experience in personal social systems, as compared with approximately 73% of the wait‐list group after 2 weeks (total score: Cohen's d = .61, p = .000) and 69% of the wait‐list group after 4 months (total score: d = .53, p = .000). The results were confirmed in per‐protocol analyses (n = 191) by the results of the EXIS.pers dimensions (Belonging, Autonomy, Accord, and Confidence) and the interpersonal scales derived from the OQ‐45 and FEP. No adverse events were reported. This RCT provides first evidence that FCSs tend to positively influence participants' experience in their social systems.     

My Long Journey Home: How the Acadian Exile Shaped My Life as a Therapist

Although attachment patterns and early relational interactions are very important in creating implicit and procedural memories, I contend, along with many authors (Gentile, 2010; Sucharov, 2012), that the historical, cultural, political, and social contexts give them meanings. Grounding myself in a relational systems theory of trauma and therapeutic healing (Brothers, 2008), I attempt to capture how a historic traumatic event in my ancestors’ lives, the Acadian Deportation, has shaped and affected my life and work as a therapist. Different themes and meanings—for example, submission and surrender (Ghent, 1990), autonomy and liberation, and restorative efforts in the aftermath of trauma that involve the reduction of complexity (Brothers, 2008)—will be revealed as part of the legacy of the historical traumatic exile and return of my Acadian ancestors. After briefly describing the tragic history of the Acadian people, I retrace my own initiatory, and never completed, journey back home as an Acadian woman therapist, through traumatic submission and its active counterpart, the impulse to dominate. A brief vignette from my work with a patient serves to illustrate how my Acadian heritage is still an active and conflictual process for me.     

Twelve-Month-Old Infants Generalize Novel Signed Labels,but Not Preferences Across Individuals

By the end of the 1st year, infants expect spoken labels to be extended across individuals and thus seem to understand words as shared conventional forms. However, it is unknown whether infants' willingness to extend labels across individuals is constrained to familiar forms, such as spoken words, or whether infants can identify a broader range of symbols as potential conventions. The present study tested whether 12-month-old infants will extend a novel sign label to a new person. Results indicate that 12-month-olds expect signed object–label relations to extend across agents but restrict object preferences to individuals. The results suggest that infants' expectations about conventional behaviors and linguistic forms are likely broad at 12 months. The implications of these findings for infants' early conceptions of conventional behaviors as well as our understanding of the initial state of the learner are considered.
