A Review of Baum's Review of Conceptual Foundations of Radical Behaviorism

Baum expressed numerous concerns about my Conceptual Foundations of Radical Behaviorism in his review. If his review were an independent submission and I were an independent referee, I would recommend that his review be rejected and that he be encouraged to revise and resubmit, once he has studied the field a bit more and clarified for himself and journal readers several important matters. I outline two sets of concerns that he might usefully clarify in his revision: (a) the important contributions of B. F. Skinner to a book about radical behaviorism, and (b) the nature of private behavioral events. In particular, the methodological behaviorism inherent in Baum's position needs to be resolved.     

Phonological similarity effects in simple and complex span tasks

Three experiments were conducted to examine the effect of phonological similarity in simple and complex memory span tasks. In Experiment 1, participants performed either a simple or a complex span task, and the memoranda within lists were either phonologically similar or distinct. Phonologically similar lists consisted of words that rhymed.The simple span task was word span. There were two complex span tasks; one was the original reading span task, and the other was a variant of reading span in which all the sentences within a list were contextually related. The classic phonological similarity decrement was observed in word span. In contrast, phonological similarity facilitation was observed in both versions of reading span. This facilitation effect was further investigated in Experiment 2 using two new versions of reading span. In Experiment 2, the sentences in reading span were either short or long, and the memoranda were presented separately from, and were unrelated to, the sentences. Again, words within phonologically similar lists rhymed, and again, facilitation was observed. In Experiment 3, phonological similarity was operationalized in terms of feature overlap, rather than rhyme. The classic phonological similarity decrement was still observed in word span, but facilitation was not observed in complex span. The results suggest that phonological similarity, when operationalized using words that rhyme, serves as a list retrieval cue and that complex span tasks are more dependent on cue-driven memory retrieval mechanisms than are simple span tasks.     

Extending the simultaneous-sequential paradigm to measure perceptual capacity for features and words

In perception, divided attention refers to conditions in which multiple stimuli are relevant to an observer. To measure the effect of divided attention in terms of perceptual capacity, we introduce an extension of the simultaneous-sequential paradigm. The extension makes predictions for fixed-capacity models as well as for unlimited-capacity models. We apply this paradigm to two example tasks, contrast discrimination and word categorization, and find dramatically different effects of divided attention. Contrast discrimination has unlimited capacity, consistent with independent, parallel processing. Word categorization has a nearly fixed capacity, consistent with either serial processing or fixed-capacity, parallel processing. We argue that these measures of perceptual capacity rely on relatively few assumptions compared to most alternative measures.     

Affect in the aftermath: how goal pursuit influences implicit evaluations

Previous research has shown that the activation of a goal leads to more implicit positivity toward goal-relevant stimuli. We examined how the actual pursuit of a goal influences subsequent implicit positivity toward such stimuli. Participants were consciously or non-consciously primed with a goal, or not, and then completed a goal-relevant task on which they succeeded or failed. We then measured their goal-relevant implicit attitudes. Those who were primed with the goal (consciously or non-consciously) and experienced success exhibited more implicit positivity toward the goal, compared with the no-goal condition. Experiencing failure in the goal priming conditions reduced implicit positivity toward the goal, indicating disengagement from the goal. We discuss the theoretical implications for understanding the role of implicit attitudes in self-regulation.     

Libertarian Free Will and the Physical Indeterminism Luck Objection

Libertarian free will is, roughly, the view that agents (or, agent-involving events) cause actions to occur or not occur: Maddy’s decision to get a beer causes her to get up off her comfortable couch to get a beer, though she almost chose not to get up. Libertarian free will notoriously faces the luck objection, according to which agential states do not determine whether an action occurs or not, so it is beyond the control of the agent, hence lucky, whether an action occurs or not: Maddy’s reasons for getting beer in equipoise with her reasons to remain in her comfortable seat do not determine that she will get up or stay seated, so it seems beyond her control, hence lucky, that she gets up. In this paper I consider a sub-set of the luck objection called the Physical Indeterminism Luck Objection, according to which indeterministic physical processes cause actions to occur or not, and agent’s lack control over these indeterministic physical processes, so agent’s lack control over, hence it is lucky, whether action occurs or not. After motivating the physical indeterminism luck objection, I consider responses from three recent event-causal libertarian models, and conclude that they fail to overcome the problem, though one promising avenue is opened up.

This paper is divided into six parts. In Section One, I minimally define libertarian free will as accepting agential indeterminism, which is the conjunction of indeterminism and agential causation, where agential indeterminism occurs when an agent’s reasons, efforts or character indeterministically cause actions. In Sections Two and Three I outline the physical indeterminism luck objection to libertarian free will, which states that sub-agential physical processes in the brain indeterministically cause actions to occur, and agents lack control over these indeterministic physical causes, so agent’s lack control over whether their actions occur. If agent’s lack control over whether actions occur, the occurrence of these actions is lucky, where this luck jeopardizes free will and moral responsibility. In Sections Four through Six I consider three recent libertarian responses to this objection—Mark Balaguer in Section Four, Chris Franklin in Section Five, and Robert Kane in Section Six. I conclude that none of these models satisfactorily overcomes the physical indeterminism luck objection, though one interpretation of Kane yields a promising avenue of reply.

     

The Oneness Beliefs Scale: Connecting Spirituality with Pro‐Environmental Behavior

The inherent unity of all phenomena, or oneness, is a central concept of mysticism, but there have heretofore been no measures of oneness beliefs. We developed the Oneness Beliefs Scale, with spiritual and physical oneness subscales. The spiritual oneness subscale fills a need in the field for a short, reliable measure of spirituality not characterized by the language of traditional Western religiousness. The physical oneness subscale allows researchers to juxtapose spiritual beliefs with a nonspiritual, materialist counterpart. We found that spiritual oneness beliefs were more strongly related to mystic experiences and spirituality than to traditional religiousness. Physical oneness was not strongly associated with either religiousness or spirituality. Both spiritual and physical oneness were positively associated with pro‐environmental attitudes but not with depression, anxiety, or negative affect. Spiritual oneness was a better predictor of pro‐environmental attitudes than was religiousness. Spiritual oneness also predicted donating to a pro‐environmental group, making this to our knowledge the first empirical study to show a positive association between a religion or spirituality measure and observed, rather than self‐reported, pro‐environmental behavior.     

Bidirectional Associations Between Parenting Behavior and Child Callous-Unemotional Traits: Does Parental Depression Moderate this Link?

The current study longitudinally examined bidirectional associations between callous-unemotional (CU) traits and parenting dimensions. This study extended the literature by examining whether parental depression moderated these relations in a pre-adolescent sample. Proposed relations were examined using a longitudinal sample of 120 aggressive children (59.6 % male) who were in the 4th grade (M?=?10.56 years, SD?=?0.56) at baseline and were followed annually over 4 years. A series of generalized estimating equation (GEE) models were used to examine proposed relations. At the first order level, corporal punishment (p?p?=?0.03) however, the inverse relations were not found. Importantly, parental depression moderated the link between corporal punishment and CU traits. Specifically, at high levels of depression, corporal punishment was predictive of increases in CU traits, but was unrelated to CU traits at low levels of depression. These findings aid in our understanding of the link between corporal punishment and CU traits by highlighting conditions under which certain parenting behaviors have an impact on CU traits, which in turn, may have important intervention implications. Further clinical implications, limitations and future directions are discussed.
