Intentional Action and the Post-Coma Patient

Detecting conscious awareness in a patient emerging from a coma state is problematic, because our standard attributions of conscious awareness rely on interpreting bodily movement as intentional action. Where there is an absence of intentional bodily action, as in the vegetative state, can we reliably assume that there is an absence of conscious awareness? Recent neuroimaging work suggests that we can attribute conscious awareness to some patients in a vegetative state by interpreting their brain activity as intentional mental action. I suggest that this change of focus, from the interpretation of motor behaviour as intentional bodily action to the interpretation of neural activity as intentional mental action, raises philosophical issues that affect the interpretation of the neuroimaging data.     

Review of the Evidence for Motivation Deficits in Youth with ADHD and Their Association with Functional Outcomes

Preeminent theories of attention-deficit/hyperactivity disorder (ADHD) suggest that motivation deficits are core underlying features of the disorder. However, it is currently unclear whether empirical evidence supports the assertion that significant group (ADHD v. comparison) differences in motivation exist or that problems with motivation contribute to the functional impairments that youth with ADHD experience. Accordingly, this review focused on evaluating and summarizing the empirical literature on the presence of motivation deficits and their association with functional outcomes in samples of youth with ADHD. Twenty studies met the review inclusion criteria. Results support the assertion that youth with ADHD have lower academic-related motivation in comparison to their peers and that motivation plays an important role in academic outcomes, with the strongest evidence to date for reading achievement. However, the available evidence is limited, and few existing studies are aligned with the much larger theoretical and empirical motivation literature in typically developing youth. Given preliminary evidence that motivation plays a role in the academic impairments of youth with ADHD, the review concludes with a discussion of whether current ADHD interventions adequately target motivation and highlights important future directions.     

Spatial representation of magnitude in humans (<Emphasis Type="Italic">Homo sapiens</Emphasis>), Western lowland gorillas (<Emphasis Type="Italic">Gorilla gorilla gorilla</Emphasis>), and American black bears (<Emphasis Type="Italic">Ursus americanus</Emphasis>)

The spatial-numerical association of response codes (SNARC) effect is the tendency for humans to respond faster to relatively larger numbers on the left or right (or with the left or right hand) and faster to relatively smaller numbers on the other side. This effect seems to occur due to a spatial representation of magnitude either in occurrence with a number line (wherein participants respond to relatively larger numbers faster on the right), other representations such as clock faces (responses are reversed from number lines), or culturally specific reading directions, begging the question as to whether the effect may be limited to humans. Given that a SNARC effect has emerged via a quantity judgement task in Western lowland gorillas and orangutans (Gazes et al., Cog 168:312–319, 2017), we examined patterns of response on a quantity discrimination task in American black bears, Western lowland gorillas, and humans for evidence of a SNARC effect. We found limited evidence for SNARC effect in American black bears and Western lowland gorillas. Furthermore, humans were inconsistent in direction and strength of effects, emphasizing the importance of standardizing methodology and analyses when comparing SNARC effects between species. These data reveal the importance of collecting data with humans in analogous procedures when testing nonhumans for effects assumed to bepresent in humans.     

The forest and the trees: Examining the association of self-compassion and its positive and negative components with psychological functioning

ABSTRACT

This paper presents two studies focusing on the link between psychological functioning and self-compassion as measured by the Self-Compassion Scale (SCS), especially in terms of SCS components that represent increased compassionate and reduced uncompassionate behavior. Study One examined this association in seven domains – psychopathology, positive psychological health, emotional intelligence, self-concept, body image, motivation, and interpersonal functioning – and found that while reduced negative self-responding had a stronger link to negative emotionality and self-evaluation than positive self-responding, they were roughly equivalent predictors in other domains. Study Two examined the association of compassionate and reduced uncompassionate behavior with sympathetic nervous system and inflammatory activity after stress, and found they equally predicted salivary alpha amylase and interleukin-6 levels in individuals after a stressful situation. Overall, results suggest that both compassionate and reduced uncompassionate self-responding are central to self-compassion and that both help to explain its link to healthy psychological functioning.     

Group Therapy, 1976: An Overview

This article discusses short-term group psychotherapy with individuals suffering from an adjustment reaction or reactive depression precipitated by genital herpes. The authors describe their experience in conducting and supervising six such therapy groups and describe several therapeutic factors that emerged as central in the treatment of this population. Among these factors are relief from isolation, the exchange of information, a challenge to defensive denial, exposure to new ideas and behaviors, an opportunity to explore the developmental issues that typically emerge, and the discussion of ethical issues.     

Stress at encoding,context at retrieval,and children’s narrative content

Research concerning the relations between stress and children’s memory has been primarily correlational and focused on memory volume and accuracy. In the current study, we experimentally manipulated 7- and 8-year-olds’ and 12- to 14-year-olds’ experienced stress during a to-be-remembered event to examine the effects of stress on the content of their memory. We further manipulated the degree of interviewer support at retrieval to determine whether it moderated the effects of stress at encoding on memory. Children’s age, gender, stress at encoding, and interviewer support all influenced the type of information included in their narrative reports. Most notably, across ages, children who experienced a more stressful event but were questioned in a supportive manner provided the largest ratio of terms representing internal states such as those about cognitions and emotions. Results suggest that how children process past events may be influenced by both the nature of the event itself and the context within which it is recalled.

A Method for the Study of Personality Reactions in Preschool age Children by Means of Analysis of their Play

This investigation studied variability in visual thresholds for six subjects for 50 consecutive days. The results show the following:

1. Session-to-session variability agrees closely with the variability estimates made by Hecht and Zegers.

2. No periodic or cyclic trends appeared for the group or for any individual subject.

3. For all six subjects for the first 15 days of testing, a learning phenomenon was observed for the mean and standard-deviation data. There was a slow rise over the last 10 days of testing for the mean, but not for the standard-deviation data. (A discussion of the possible causes of the rise of the mean over the last 10 days suggested the influence of extraneous factors, such as boredom and fatigue.)

4. No effect of the menstrual cycle upon the threshold values was found.

Flicker Induction and the Role of Molar Properties in the Critical Flicker Frequency

This experiment investigated the effects of peer vs. adult frustration on aggressive responses of eight-year-old boys. In addition, the effect of frustration vs. nonfrustration on aggressive responding was tested.

In two experimental conditions, groups of four boys were brought into a room and read instructions preparing them for a game-competition situation. Either a peer or an adult confederate disrupted the group's goal completion. A control condition without disruption was also used.

Considerably more aggression was expressed in the peer condition than in the adult condition, on the basis of the aggression category of the Rosenzweig Picture-Frustration Test, Children's Form (20). Frustration in general led to significantly more aggression than no frustration.

The results indicated that boys of middle childhood are more attentive to and are likely to exhibit more aggressive reaction to peer frustration than adult frustration. In addition, frustration in general yielded more aggressive reaction than no frustration, supporting the original frustration-aggression theory proposed by Dollard et al. (8).
