Spurious Causal Kinds: A Problem for the Causal-Power Conception of Kinds

There is an assumption common in the philosophy of mind literature that kinds in our sciences—or causal kinds, at least—are individuated by the causal powers that objects have in virtue of the properties they instantiate. While this assumption might not be problematic by itself, some authors take the assumption to mean that falling under a kind and instantiating a property amount to the same thing. I call this assumption the “Property-Kind Individuation Principle”. A problem with this principle arises because there are cases where we can sort objects by their possession of common causal powers, and yet those objects do not intuitively form a causal kind. In this short note, I discuss why the Property-Kind Individuation Principle is thus not a warranted metaphysical assumption.     

Understanding pro‐environmental intentions by integrating insights from social mobility,cosmopolitanism, and social dominance

To offer an integrative account bridging individuals’ sociocultural orientations with pro‐environmentalism, the current research tested the mediating and moderating relationships among pro‐environmental intentions and three person‐level factors: perceived social mobility, cosmopolitan orientation, and social dominance orientation (SDO). With a Singaporean college student sample (N = 220), we found support for the hypothesized second‐stage moderation model that perceived social mobility positively predicts cosmopolitan orientation, and in turn, cosmopolitan orientation is moderated by SDO to positively predict pro‐environmental intentions. Specifically, lower levels of SDO strengthen the pro‐environmental advantages of endorsing higher levels of cosmopolitan orientation. These findings add novel knowledge to the environmental psychology literature by advancing an integrative approach that demonstrates how the interplay of people's perceptions about the social, cultural, and group standing impacts their likelihood to engage in pro‐environmental actions. We discuss the implications that an egalitarian worldview toward other cultures, social groups, and human–nature relations might be the key to addressing the global challenge of climate change.

School Counselors,Multiple Student Deaths,and Grief: A Narrative Inquiry

A team of 5 school counselors were interviewed to learn how they professionally and personally experienced the deaths of multiple students in 1 year in their school while attending to the needs of the school community. By using narrative inquiry, 5 themes emerged from the analysis: gravity of the losses, logistics of care, personal vs. professional conflicts, increased student cohesion, and efficacy. Recommendations for counselor preparation, research, and counseling practice are offered.     

The impact of proficiency testing information and error aversions on the weight given to fingerprint evidence

Fingerprint examiners regularly participate in tests designed to assess their proficiency. These tests provide information relevant to the weight of fingerprint evidence, but no prior research has directly examined how jurors react to proficiency testing information. Using a nationally representative sample of American adults, we examined the impact of proficiency testing information on the weight given to the opinions of fingerprint examiners by mock jurors considering a hypothetical criminal case. The fingerprint examiner's level of performance on a proficiency test (high, medium, low, or very low), but not the type of error committed on the test (false positive identifications, false negative identifications, or a mix of both types of error), affected the weight that jury‐eligible adults gave to an examiner's opinion that latent fingerprints recovered from a crime scene matched the defendant's fingerprints, which in turn affected judgments about the defendant's guilt. Jurors who had no information about proficiency gave similar weight to the testimony as jurors exposed to highly proficient examiners, suggesting that jurors assume fingerprint examiners perform at high levels of proficiency unless informed otherwise. We also found that a plurality of Americans deems false acquittals just as aversive as false convictions and a significant minority deems false acquittals more serious. These differences in error aversions predicted differences in evidentiary assessments, suggesting that error aversions of jurors may play an important role in criminal trials.     

Tough guys finish last: the perils of a distributive reputation

Reputations are socially constructed labels that provide representations (or schema), which organize our images of another person. We look at how reputations influence negotiations by examining their impact on negotiator cognitions, behaviors, and subsequent outcomes. We randomly paired relative novices with relative experts to negotiate over email, telling half the novices that their counterparts were experts in distributive negotiation (i.e., the art of claiming value). Findings supported our predictions that novices whose counterparts had a distributive reputation judged these counterparts' intentions in a more negative light and used more distributive and fewer integrative tactics than the control group novices. This resulted in lower joint gains in the distributive reputation condition than in the control condition. Notably, the more experienced negotiators were able to extract more individual value from the deal, but not when they had a reputation for being distributive. In other words, the fictitious distributive reputation prevented participants from capitalizing on their real negotiation expertise advantage.     

Age, Race, and Implicit Prejudice: Using Process Dissociation to Separate the Underlying Components

ABSTRACT— Older adults express greater prejudice than younger adults, but it is not clear why. In a community-based sample, we found that older White adults demonstrated more racial prejudice on an implicit measure, the race Implicit Association Test, than did younger adults. Process-dissociation procedures indicated that this difference in implicit prejudice was due to older adults having less control of their automatic prejudicial associations rather than stronger automatic prejudicial associations. Furthermore, this age difference in control was mediated by age-related deficits in inhibitory ability. White participants showed stronger automatic prejudicial associations than did Black participants.     

Semantic and subword priming during binocular suppression

In general, stimuli that are familiar and recognizable have an advantage of predominance during binocular rivalry. Recent research has demonstrated that familiar and recognizable stimuli such as upright faces and words in a native language could break interocular suppression faster than their matched controls. In this study, a visible word prime was presented binocularly then replaced by a high-contrast dynamic noise pattern presented to one eye and either a semantically related or unrelated word was introduced to the other eye. We measured how long it took for target words to break from suppression. To investigate word-parts priming, a second experiment also included word pairs that had overlapping subword fragments. Results from both experiments consistently show that semantically related words and words that shared subword fragments were faster to gain dominance compared to unrelated words, suggesting that words, even when interocularly suppressed and invisible, can benefit from semantic and subword priming.     

Impaired long-term potentiation and enhanced neuronal excitability in the amygdala of CaV1.3 knockout mice

Previously, we demonstrated that mice in which the gene for the L-type voltage-gated calcium channel Ca_V1.3 is deleted (Ca_V1.3 knockout mice) exhibit an impaired ability to consolidate contextually-conditioned fear. Given that this form of Pavlovian fear conditioning is critically dependent on the basolateral complex of the amygdala (BLA), we were interested in the mechanisms by which Ca_V1.3 contributes to BLA neurophysiology. In the present study, we used in vitro amygdala slices prepared from Ca_V1.3 knockout mice and wild-type littermates to explore the role of Ca_V1.3 in long-term potentiation (LTP) and intrinsic neuronal excitability in the BLA. We found that LTP in the lateral nucleus (LA) of the BLA, induced by high-frequency stimulation of the external capsule, was significantly reduced in Ca_V1.3 knockout mice. Additionally, we found that BLA principal neurons from Ca_V1.3 knockout mice were hyperexcitable, exhibiting significant increases in firing rates and decreased interspike intervals in response to prolonged somatic depolarization. This aberrant increase in neuronal excitability appears to be at least in part due to a concomitant reduction in the slow component of the post-burst afterhyperpolarization. Together, these results demonstrate altered neuronal function in the BLA of Ca_V1.3 knockout mice which may account for the impaired ability of these mice to consolidate contextually-conditioned fear.
