Spatial grouping resolves ambiguity to drive temporal recalibration

Cross-modal temporal recalibration describes a shift in the point of subjective simultaneity (PSS) between 2 events following repeated exposure to asynchronous cross-modal inputs--the adaptors. Previous research suggested that audiovisual recalibration is insensitive to the spatial relationship between the adaptors. Here we show that audiovisual recalibration can be driven by cross-modal spatial grouping. Twelve participants adapted to alternating trains of lights and tones. Spatial position was manipulated, with alternating sequences of a light then a tone, or a tone then a light, presented on either side of fixation (e.g., left tone--left light--right tone--right light, etc.). As the events were evenly spaced in time, in the absence of spatial-based grouping it would be unclear if tones were leading or lagging lights. However, any grouping of spatially colocalized cross-modal events would result in an unambiguous sense of temporal order. We found that adapting to these stimuli caused the PSS between subsequent lights and tones to shift toward the temporal relationship implied by spatial-based grouping. These data therefore show that temporal recalibration is facilitated by spatial grouping.     

Who you could have known: divine hiddenness,epistemic counterfactuals,and the recalcitrant nature of natural theology

We argue there is a deep conflict in Paul Moser’s work on divine hiddenness (DH). Moser’s treatment of DH adopts a thesis we call SEEK: DH often results from failing to seek God on His terms. One way in which people err, according to Moser, is by trusting arguments of traditional natural theology to lead to filial knowledge of God. We argue that Moser’s SEEK thesis commits him to the counterfactual ACCESS: had the atheist sought after God in harmony with how God reveals himself, she would have had access to filial knowledge of God. By failing to incorporate arguments or propositional evidence for God’s existence, Moser’s account leaves the doubting seeker without any evidential reason to think that either SEEK or ACCESS is true. Without this rational motivation in place, the doubting seeker is unlikely to seek after God in the way ACCESS describes. We argue that natural theology provides an evidential epistemic aid to motivate persons to seek God the way ACCESS describes. Thus, Moser is mistaken. Such arguments can be evidentially helpful in coming to know God. In conclusion, we explain how our reply naturally fits how we form and maintain trusting interpersonal relationships with others.     

Behavioral Activation for a Breast Cancer Patient with Major Depression and Coexistent Personality Disorder

Behavioral activation is an empirically validated treatment for depression, with recent applications toward other psychological and medical conditions. However, modification to the treatment protocol may be necessary when symptoms, environment, or personality necessitate. This feasibility study applied Behavioral Activation Treatment for Depression (BATD) in a case of a woman with recurrent major depression and obsessive–compulsive personality disorder (OCPD) undergoing breast cancer treatment. A quasi-experimental design was used, comparing supportive psychotherapy (while she received radiation therapy) followed by eight sessions of BATD. Treatment was designed in accordance with patient and therapist goals of increasing exercise, decreasing fatigue, and reducing interference due to perfectionistic behaviors. The patient exhibited resistance to initiation of BATD, related to symptoms of OCPD, which necessitated modification of treatment strategies and scheduling. Following BATD, the patient reported a significant reduction in depressive symptoms, physical problems, and role limitations—gains not observed following supportive therapy. In addition, she demonstrated less psychological rigidity and interference due to OCPD symptoms within the therapeutic relationship and other interpersonal relationships. Consistent with previous research, results indicate BATD may effectively treat individuals with complex clinical presentations that include personality disorder pathology. In addition, methods of modification to BATD are discussed, as well as future directions for research in this area.     

Dissociable interference-control processes in perception and memory

Control over interference is a pervasive feature of cognitive life. Central to research on interference control has been the identification of its underlying mechanisms. Investigations have focused on processes that filter out distracting perceptual information, leading to negative priming, and processes that discard intruding memories that cause proactive interference. Theories differ regarding whether or not a single process during episodic retrieval underlies both negative priming and the resolution of proactive interference. Using functional magnetic resonance imaging, we combined both phenomena into a single paradigm and found that occipital cortex shows activation uniquely related to negative priming, whereas activation increases in left lateral prefrontal cortex are uniquely associated with proactive interference. This pattern of results contradicts theories that rely on a single process to account for both phenomena. However, results also showed common recruitment of right dorsolateral prefrontal cortex and parietal regions and therefore suggest that some control processes are shared.     

On the additive effects of stimulus quality and word frequency in lexical decision: evidence for opposing interactive influences revealed by RT distributional analyses

The joint effects of stimulus quality and word frequency in lexical decision were examined in 4 experiments as a function of nonword type (legal nonwords, e.g., BRONE, vs. pseudohomophones, e.g., BRANE). When familiarity was a viable dimension for word-nonword discrimination, as when legal nonwords were used, additive effects of stimulus quality and word frequency were observed in both means and distributional characteristics of the response-time distributions. In contrast, when the utility of familiarity was undermined by using pseudohomophones, additivity was observed in the means but not in distributional characteristics. Specifically, opposing interactive effects in the underlying distribution were observed, producing apparent additivity in means. These findings are consistent with the suggestion that, when familiarity is deemphasized in lexical decision, cascaded processing between letter and word levels is in play, whereas, when familiarity is a viable dimension for word-nonword discrimination, processing is discrete.     

Nonstrategic contributions to putatively strategic effects in selective attention tasks

Proportion compatible manipulations are often used to index strategic processes in selective attention tasks. Here, a subtle confound in proportion compatible manipulations is considered. Specifically, as the proportion of compatible trials increases, the ratio of complete repetitions and complete alternations to partial repetitions increases on compatible trials but decreases on incompatible trials. This confound is demonstrated to lead to an overestimation in the magnitude of the proportion compatible effect in the context of both a Stroop and a Simon task. Implications for previous research and directions for future research using proportion compatible manipulations are discussed.     

Darwin's mistake: explaining the discontinuity between human and nonhuman minds

Over the last quarter century, the dominant tendency in comparative cognitive psychology has been to emphasize the similarities between human and nonhuman minds and to downplay the differences as "one of degree and not of kind" (Darwin 1871). In the present target article, we argue that Darwin was mistaken: the profound biological continuity between human and nonhuman animals masks an equally profound discontinuity between human and nonhuman minds. To wit, there is a significant discontinuity in the degree to which human and nonhuman animals are able to approximate the higher-order, systematic, relational capabilities of a physical symbol system (PSS) (Newell 1980). We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain. We propose a representational-level specification as to where human and nonhuman animals' abilities to approximate a PSS are similar and where they differ. We conclude by suggesting that recent symbolic-connectionist models of cognition shed new light on the mechanisms that underlie the gap between human and nonhuman minds.
