The Home-Based Occupational Therapy Intervention in the Alzheimer's Disease Multiple Intervention Trial (ADMIT)

There is no way to prevent functional declines related to Alzheimer's Disease (AD). The use of occupational therapy (OT) has been shown to be successful in managing some aspects of AD. We added home-based OT to evidence-based best practice for AD with the aim of delaying functional decline in people with AD. OT was delivered in the home to a caregiver dyad including the person with AD and her/his caregiver. This article describes the OT intervention for the AD Multiple Intervention Trial, a parallel randomized controlled trial. We include baseline data on the 180 caregiver dyads.     

Does perceived ability to deceive = ability to deceive? Predictive validity of the perceived ability to deceive (PATD) scale

This research investigated whether the perceived ability to deceive (PATD) scale predicts ability to deceive in a vocational testing context. Using a quasi-experimental design, participants (N = 85 student and community members) completed the PATD scale and a personality measure under standard instructions before being asked to fake the personality measure as if they were applying for a job in the police force. Based on extant research, successful faking was operationalised as elevated scores on conscientiousness and extraversion and reduced scores on neuroticism. Analysis via independent t-test did not support the hypothesis that PATD predicts faking success. Future research should consider the relationship between PATD and intention to fake, as well as extend examination of PATD to other deception-related contexts.     

Effects of 7.5% CO2 inhalation on allocation of spatial attention to facial cues of emotional expression

Increased vigilance to threat-related stimuli is thought to be a core cognitive feature of anxiety. We sought to investigate the cognitive impact of experimentally induced anxiety, by means of a 7.5% CO₂ challenge, which acts as an unconditioned anxiogenic stimulus, on attentional bias for positive and negative facial cues of emotional expression in the dot-probe task. In two experiments we found robust physiological and subjective effects of the CO₂ inhalation consistent with the claim that the procedure reliably induces anxiety. Data from the dot-probe task demonstrated an attentional bias to emotional facial expressions compared with neutral faces regardless of valence (happy, angry, and fearful). These attentional effects, however, were entirely inconsistent in terms of their relationship with induced anxiety. We conclude that the previously reported poor reliability of this task is the most parsimonious explanation for our conflicting findings and that future research should develop a more reliable paradigm for measuring attentional bias in this field.     

Disequilibrium in the mind,disharmony in the body

Although it is generally acknowledged that experiences of frustration, confusion, and anxiety are embodied phenomena, very little is known about how these processes modulate presumably unconscious, but constantly present, subtle bodily movement. We addressed this problem by tracking the low-level dynamics of body movement, using 1/f noise, pink noise, or “fractal scaling”, during naturalistic experiences of affect in two studies involving deep learning and effortful problem-solving. Our results indicate that body movement fluctuations of individuals experiencing cognitive equilibrium was characteristic of correlated pink noise, but there was a whitening of the signal when participants experienced states that are diagnostic of cognitive distress such as anxiety, confusion, and frustration. We orient our findings within theories that emphasise the embodied nature of cognition and affect and with perspectives that view affective and cognitive processes as emergent products of a self-organising dynamical system (the brain) that is inextricably coupled to the body.     

Ethical Embodiment and Moral Reasoning: A Challenge to Peter Singer

This paper addresses Peter Singer's claim that cognitive ability can function as a universal criterion for measuring moral worth. I argue that Singer fails to adequately represent cognitive capacity as the object of moral knowledge at stake in his theory. He thus fails to put forth credible knowledge claims, which undermines both the trustworthiness of his moral theories and the morality of the actions called for by these theories. I situate Singer's methods within feminist critiques of moral reasoning and moral epistemology, and argue that Singer's methods are problematic for moral reasoning because they abstract from their object valuable contextual features. I further develop this claim by showing the importance of embodiment for the construal of objects of moral knowledge. Finally, I develop the moral and scholarly implications of this critique. By showing that the abstract, universal methods of reasoning Singer employs cannot credibly construe the objects of ethical inquiry, I call into question the validity of these methods as a means to moral knowledge in general. Furthermore, since moral reasoning takes place within an embodied moral landscape, it is itself a moral enterprise. Singer's moral reasoning, and ours, must be held accountable for its knowledge claims as well as its concrete effects in the world.     

A Multicultural Application of Attachment Theory with Immigrant Families: Contextual and Developmental Adaptations

This article explores attachment theory from a multicultural perspective to highlight adaptive considerations for immigrant families. The specific considerations of the theory reviewed are (1) attachment sensitivity based on social and cultural context and (2) the effect of maturation on families’ developmental needs and how this can be integrated within context. A case conceptualization of a Bosnian immigrant family living within the United States will highlight potential variations in the adaptation process. How therapists can support in providing culturally-sensitive applications of attachment theory to promote family relationships will be discussed.     

Irksome assertions

The Knowledge Account of Assertion (KAA) says that knowledge is the norm of assertion: you may assert a proposition only if you know that it’s true. The primary support for KAA is an explanatory inference from a broad range of linguistic data. The more data that KAA well explains, the stronger the case for it, and the more difficult it is for the competition to keep pace. In this paper we critically assess a purported new linguistic datum, which, it has been argued, KAA well explains. We argue that KAA does not well explain it.     

Whom do children copy? Model-based biases in social learning

This review investigates the presence of young children’s model-based cultural transmission biases in social learning, arguing that such biases are adaptive and flexible. Section 1 offers five propositions regarding the presence and direction of model-based transmission biases in young children’s copying of a model. Section 2 discusses the cognitive abilities required for differing model-based biases and tracks their development in early childhood. Section 3 suggests future areas of research including considering the social aspect of model-based biases and understanding their use within a comparative perspective.     

Ventral encoding of functional affordances: A neural pathway for identifying errors in action

Functional tool usage is a critical aspect of our daily lives. Not only must we know which tools to use for a specific action goal, we must also know how to manipulate those tools in meaningful way to achieve the goal of the action. The purpose of this study was to identify the regions of the brain critical to supporting the process of understanding errors in tool manipulation. Using fMRI, neural activations were recorded while subjects were presented with images demonstrating typical action scenes (screwdriver used on a screw), but with the tool being manipulated either correctly (screwdriver held by handle) or incorrectly (screwdriver held by bit rather than handle). Activations in fMRI for identifying correct over incorrect tool manipulation were seen along the canonical parietofrontal action network, while activations for identifying incorrect over correct tool manipulation were primarily seen at superior temporal areas and insula. We expand our hypotheses about ventral brain networks identifying contextual error to further suggest mechanisms for understanding functional tool actions, which collectively we regard as functional affordances. This proposes a fundamental role for ventral brain areas in functional action understanding.     

Busy lifestyles and mammography screening: Time pressure and women’s reattendance likelihood

Time pressure is often cited as a reason for non-attendance at mammography screening, although evidence from other areas of psychology suggests that time pressure can improve performance when barriers such as time pressure provide a challenge. We predicted that time pressure would negatively predict attendance in women whose self-efficacy for overcoming time pressure is low, but positively predict attendance when self-efficacy is high. Time pressure was operationalised as the self-reported number of dependent children and others, and average number of working hours per week. Australian women were surveyed after being invited to attend second or subsequent screenings at a free public screening service, and subsequent attendance monitored until six months after screening was due. The majority (87.5%) attended screening. Women with more dependent children and higher self-efficacy showed greater attendance likelihood, and women with fewer non-child dependants and lower self-efficacy were less likely to attend. Working hours did not predict attendance. Findings provide partial support for the idea that time pressure acts as a challenge for women with high self-efficacy.
