A transfer of self-discrimination response functions through equivalence relations

The present study tested the idea that human self-discrimination response functions may transfer through equivalence relations. Four subjects were trained in six symbolic matching-to-sample tasks (if see A1, choose B1; A1-C1, A2-B2, A2-C2, A3-B3, A3-C3) and were then tested for the formation of three equivalence relations (B1-C1, B2-C2, B3-C3). Two of the B stimuli (B1 and B2) were then used to train two different self-discrimination responses using either detailed instructions (Subjects 1 to 3) or minimal instructions (Subject 4) on two complex schedules of reinforcement (i.e., subjects were trained to pick the B1 stimulus if they had not emitted a response, and to pick the B2 stimulus if they had emitted one or more responses on the previous schedule). All 4 subjects showed the predicted transfer of self-discrimination response functions through equivalence relations (i.e., no response on the schedule, pick C1; one or more responses on the schedule, pick C2). Subjects also demonstrated this transfer when they were required to discriminate their schedule performance before exposure to the schedule (i.e., “what I intend to do”). Four control subjects were also used in the study. Two of these (Subjects 5 and 6) were not exposed to any form of matching-to-sample training and testing (nonequivalence controls). The 2 remaining subjects (7 and 8) were exposed to matching-to-sample training and testing that incorporated stimuli not used during the transfer test; C1 and C2 were replaced by N1 and N2 during the matching-to-sample training and testing, but C1 and C2 were used for the transfer tests (equivalence controls). All 4 subjects failed to produce the self-discrimination transfer performances observed with the experimental subjects.     

Characteristic patterns of verbal memory function in patients with Huntington's disease

Various aspects of verbal memory in patients with Huntington's disease (HD) were studied using the California Verbal Learning Test (CVLT). We tested if the level and interplay between 5 parameters of different memory mechanisms and processes were sufficiently specific to allow acceptable discrimination between patients with HD, patients with Parkinson's disease (PD), and patients without known CNS disease or injury. The HD-patients were characterized by a deficit in acquisition, elevated rates of recall errors and increased use of a passive learning strategy. Preserved aspects were shown in retention over time, interference effects and recognition relative to recall. Employing multivariate classification and validation techniques, the 5 CVLT-features demonstrated good separability between the HD-patients and the control patients. Qualitative similarities between subgroups were suggested, but more disease-specific data seemed necessary in further studies. A number of findings suggested a defect in the active organization of items to be encoded and recalled in HD. Similar findings in the PD-group might indicate that this trait is common in several types of 'subcortical dementia'.     

Ahistorical intentional content

One of the main problems of current theory of intentionality concerns the possibility of ahistorical intentional content, that is, content in the absence of any developmental history of the respective item. Biosemanticists like Millikan (1984) argue that content is essentially historical, while computationalists like Cummins (1989) hold that a system's current ahistorical state alone determines content. In the present paper, this problem is discussed in terms of some popular cosmic accident thought experiments, and the conceptual framework of these experiments is enriched by some new versions like accidental duplicates without any preexisting original. As a result of these evaluations, it is argued that for an item to bear intentional content it is necessary to have a function in the forward-looking sense introduced by Bigelow & Pargetter (1987). Since historicity is not necessary for functionality, ahistorical states can be intentional as long as they have functions. This result does not support computationalism, since functionality cannot be determined in terms of current ashistorical state alone, but only with reference to the present and future environmental context of the cognitive system that harbours these states.     

体感游戏促进儿童的执行功能：运动强度和认知参与的作用

为了考察体感游戏促进儿童执行功能的作用机制, 采用2(运动强度：高/低) × 2(认知参与：高/低) × 3(测量时间：前测、一次性训练后测、长期训练后测)的三因素混合实验设计, 对122名4~6岁儿童进行6周(每周3次)的体感游戏训练。结果发现：在一次性训练中, 体感游戏中的运动强度而不是认知参与显著促进儿童执行功能, 尤其是工作记忆; 在长期干预中, 体感游戏中的运动强度和认知参与都显著促进儿童执行功能, 且认知参与的作用大于运动强度。这一结果不但验证了体感游戏对儿童执行功能的益处, 并且阐明了体感游戏中的哪些特征能对儿童执行功能具有短期的和长期的效果。     

A comprehensive model of women’s social cognition and responsiveness to infant crying: Integrating personality,emotion, executive function,and sleep

Disparate lines of research suggest that women’s (a) emotion regulation and personality, (b) executive function and (c) sleep may be important predictors of mothers’ cry responding in part through their effects on social cognition. However, the extent to which each contributes to cry responding independently remains unknown. We examined this question in a convenience sample of 109 nulliparous undergraduate women. Women completed online surveys to assess personality and emotion dysregulation traits, then visited the lab for a testing session during which they reported on sleep the night before and reactions to videotapes of crying infants and completed computerized working memory and inhibitory control tasks under challenging noise conditions (exposure to traffic and cry sounds). Results indicate that women’s positive personality and higher working memory were associated with higher levels of infant-oriented cry processing (i.e., accurate distress detection, empathy and situational/emotional attributions about distress), which in turn was associated with higher intended responsiveness to infant crying. Emotion dysregulation and deficits in inhibitory control were associated with higher levels of self-oriented cry processing (i.e., anger, anxiety, negative and emotion minimizing attributions in response to infant distress), which in turn was associated with lower cry responsiveness. Short-term sleep deprivation was associated with lower intended responsiveness via the above path from poorer inhibitory control to heightened self-oriented cry processing. Findings suggest that sleep, emotional and cognitive factors are associated with cry processing and subsequent responsiveness independent of one another.     

Coronavirus: does its activation of archetypes of evil cause added psychological suffering?

Fear and grief caused by the pandemic have produced a powerful unconscious narrative in the collective psyche that the coronavirus is driven by an innately evil, and possibly divine, force. The resulting archetypal dimension of fear causes an extra layer of psychological suffering in individuals. This paper discusses how and why this narrative was created and why it is so compelling by looking at 1) the myth-making nature of the human psyche, 2) the psychodynamics of fear that drive the narrative, 3) the properties of the coronavirus and the pandemic that activate negative poles of some archetypes, in particular, archetypes of evil, and 4) asking how analytical psychology can help ease psychological suffering caused by these negative narratives, where one possibility is to invoke the transcendent function. The author’s personal experiences as both biochemist and analytical psychologist elucidate how the transcendent function can promote healing.     

Validity of the strategic management simulations to predict real-world productivity

The performance of individual businesses and the economy as a whole hinges on the productivity of human capital, yet measuring productivity at an individual level has proved difficult. The Strategic Management Simulation (SMS) methodology comprises several decision-making assessment tools that have been used for several decades to estimate real-world productivity. Performance on productivity measures using a shorter version of the SMS methodology was gathered from a sample of 111 knowledge workers from major corporations in the U.S. and compared with their income level. In linear models, every percentile increase in SMS performance was associated with a $791–$1,113 increase in income in each of the four domains of decision-making performance provided by the SMS tool. The models had R²’s ranging from 0.65 to 0.75, indicating high levels of correlation between SMS performance and income levels. This study is the first to show linear relationships between SMS performance and other indicators of productivity, indicating that the SMS is a valid predictor of productivity and that SMS scores can be used to predict job satisfaction and performance.     

Murray Sidman's contributions to clinical behavior analysis

Murray Sidman was not himself a clinician nor directly involved in clinical research. Nevertheless, his experimental and conceptual work, especially in the area of stimulus equivalence, profoundly influenced the development of clinical behavior analysis. Before his work on stimulus equivalence, clinicians with a behavior analytic world view working with verbally sophisticated humans, were making some progress in understanding clinical phenomena and in developing innovative therapies. However, given the obvious and predominant role of verbal processes in both the development and treatment of clinical problems, that progress was constrained by the existing behavior analytic account of verbal behavior. Most fundamentally, it was hard to understand how, in the apparent absence of direct training, verbal events, even novel verbal events, acquire the functions of the nonverbal events that they stand for or represent. Sidman's work on stimulus equivalence, especially the transfer (transformation) of functions, offered an answer and thereby provided a conceptual framework of symbolic behavior around which clinical behavior analysis could cohere and develop.     

Nonsimultaneous stimulus presentations and their role in listener naming

Previous studies on naming have presented the object and its name simultaneously during both training and testing, and thus the training component may establish a transformation of function directly between the object and the name. Successful tests for listener naming may thus not require the emergence of a novel (entailed) transformation of function. The current study aimed to control for this possibility by presenting the object and the name sequentially and nonsimultaneously. Eight typically developing toddlers participated in the current study. During name training, objects and names were presented nonsimultaneously, and all participants failed to emit listener-naming responses during the first test session. Subsequently, 4 participants received multiple exemplar training, which led to improvements in listener naming for all 4; and speaker naming for only 1 participant. As a control condition, the remaining 4 participants were tested repeatedly, without multiple exemplar training, and did not show any consistent improvements in their listener or speaker performances. Multiple exemplar training thus appeared to be effective in establishing generalized listener responses, which involved generating entailed transformation of functions. The strategy of using nonsimultaneous stimulus presentations could allow for greater precision in identifying the behavioral processes involved in listener-naming.
