The Philosophical Foundations of Humanistic Psychology: A Reply to McMullen

McMullen (1982) attempted in his critique of humanistic psychology to attack its philosophical foundations, taking these to be phenomenology and a doctrine of self determination. In this paper we argue that McMullen has misrepresented the philosophical position of the humanists, then we examine McMullen's own philosophical assumptions. We show that he has assumed the philosophy of empirical realism which we argue is inadequate as a foundation for science. It is shown that it is the inadequacy of McMullen's assumptions which underlies his failure to comprehend the position of the humanists. We then present a version of theoretical realism and show how, in terms of this, a conception of being can be justified which allows for the emergence of hierarchical order. On the basis of this conception of being we reassess the nature of self-determination and motivation, showing how, in opposition to both the empirical realism of McMullen and the philosophical dualism of conventional humanistic psychology, a naturalistic form of humanistic psychology is justified.     

Social Function and Autism Spectrum Disorder in Children and Adults with Neurofibromatosis Type 1: a Systematic Review and Meta-Analysis

In light of the proliferation of recent research into social function in neurofibromatosis type 1 (NF1), a systematic review and meta-analysis is required to synthesise data and place findings within the context of a theoretical framework. This paper reviews findings from research into social function and autism spectrum disorder (ASD) in children and adults with NF1 and integrates these findings with the Socio-Cognitive Integration Abilities Model (SOCIAL). It also critically appraises links between social outcomes, internal and external factors moderating social functioning, cognitive domains implicated in social functioning, and underlying neural pathology in NF1. A systematic literature search conducted in MedLine (Ovid), PsycINFO (Ovid), Embase (Ovid), and PubMed electronic databases yielded 35 papers that met inclusion criteria for the systematic review. Out of these papers, 22 papers provided sufficient data for meta-analysis. Findings from this review and meta-analysis provide evidence that children and adults with NF1 exhibit significantly higher prevalence and severity of social dysfunction and ASD symptomatology. To date, very few studies have examined social cognition in NF1 but results indicate the presence of both perceptual and higher-level impairments in this population. The results of this review also provide support for age, gender, and comorbid ADHD as moderating factors for social outcomes in NF1. Suggestions for future research are offered to further our understanding of the social phenotype in NF1 and to facilitate the development of targeted interventions.     

The Family Stress Model as it Applies to Custodial Grandfamilies: A Cross Validation

There is scant research on how the parenting practices of custodial grandmothers affect the psychological adjustment of grandchildren in their care. Yet, the findings from a handful of prior studies suggest the relevance of the Family Stress Model (FSM) to these caregivers. The present study further tested the FSM with baseline data from 343 custodial grandmothers (M_age?=?58.5 years) enrolled in a clinical trial of the efficacy of interventions for improving the well-being of their families. Not only was this “help-seeking” sample atypical of prior FSM studies, but also unique to the present study was our addition of multiple parenting practices, self-reported and clinical ratings of grandmothers’ distress, and reports of grandchildren’s internalizing and externalizing difficulties from grandchildren and grandmothers. Mplus 7.31 was used to test a model where the effect of grandmother distress on grandchildren’s internalizing and externalizing difficulties was hypothesized to be indirect through five distinct parenting practices. The findings regarding both the measurement and structural models fit the observed data well, and invariance was largely found across grandchildren’s gender and age (4–7 vs. 8–12). Although grandchildren’s self-reported internalizing and externalizing difficulties were unrelated to grandmothers’ distress and parenting practices, the grandmothers’ reports of these outcomes were generally related to their own distress and parenting practices as hypothesized. However, considerable variation was found across the five parenting practices in terms of their relationships to the other FSM constructs. We conclude that data from multiple informants and measures of assorted parenting practices are essential to future research and practice.     

“I Didn’t Expect to Learn as Much as I Did”: Rewards of Caregiving in Young Adulthood

While much attention is given to unpaid caregivers in midlife, there is a notable gap in the literature regarding young adults in family caregiving roles. Although two out of 5 family caregivers are between the ages of 18 and 40, we know relatively little about these younger relatives providing support to ill and disabled family members. Understanding the experiences of this under-researched population is critical to effective social service provision for this new wave of caregivers. In addition, the challenges associated with caregiving are well documented, yet examining the positive aspects of caregiving is necessary to provide a balanced picture of caregiving. The purpose of this qualitative study was to explore the gains experienced by family caregivers in young adulthood. In-depth telephone interviews were conducted with a diverse sample of 22 individuals who were (or had previously been) caregivers while in young adulthood. Analysis of the data resulted in identification of four themes concerning gains experienced by young adult caregivers: a strengthening of family relationships, character growth, personal satisfaction in the care provided, and material benefit. This study sheds some understanding on rewards experienced by a subgroup of family caregivers who has received little attention—young adult caregivers.     

Dissociable learning processes in comparative psychology

Comparative and cognitive psychologists interpret performance in different ways. Animal researchers invoke a dominant construct of associative learning. Human researchers acknowledge humans’ capacity for explicit-declarative cognition. This article offers a way to bridge a divide that defeats productive cross-talk. We show that animals often challenge the associative-learning construct, and that it does not work to try to stretch the associative-learning construct to encompass these performances. This approach thins and impoverishes that important construct. We describe an alternative approach that restrains the construct of associative learning by giving it a clear operational definition. We apply this approach in several comparative domains to show that different task variants change—in concert—the level of awareness, the declarative nature of knowledge, the dimensional breadth of knowledge, and the brain systems that organize learning. These changes reveal dissociable learning processes that a unitary associative construct cannot explain but a neural-systems framework can explain. These changes define the limit of associative learning and the threshold of explicit cognition. The neural-systems framework can broaden empirical horizons in comparative psychology. It can offer animal models of explicit cognition to cognitive researchers and neuroscientists. It can offer simple behavioral paradigms for exploring explicit cognition to developmental researchers. It can enliven the synergy between human and animal research, promising a productive future for both.
