The Role of Philosophy in Academic Ethics

This paper seeks to provide some of the roles of philosophy in the field of academic ethics.     

Offensiphobia

This essay provides a critical philosophical assessment of “offensiphobia,” which is the belief that higher educational academic freedom ought to be to some important extent censured because of the mere offensiveness of certain kinds of expressions, whether those expressions are perceived as being racist, sexist, etc., effectively holding that the offensiveness of such expressions is a sufficient condition to justify its prohibition. This paper concisely sets forth the general legal parameters of the United States constitutional First Amendment right to freedom of expression. Subsequently, it follows Joel Feinberg in distinguishing between harms and offenses and explains why the law should only protect against harms and not mere offenses (e.g., language which offends but does not harm). Following this, logical and moral considerations (some based on considerations of philosophy of language) are brought to bear in order to further assess the implicitly supporting view of offensiphobia that faculty and students in higher educational contexts have a claim right to not be offended correlated with a duty of others to not offend them. For example, the use-mention distinction is discussed in order to explain why linguistic intent is crucial for the determination of what genuinely counts as being racist, sexist or otherwise offensive discourse. In the end, there are a variety of reasons for thinking that there is no moral right to not be offended correlated with a moral duty of others to not offend in higher educational contexts and that the law and public policy ought to track this fact. Without a right to not be offended, those who seek to curtail higher educational academic freedom rights by way of censorship stand on unreasonable ethical grounds to do so, though the law seems to permit private institutions to delimit offensive expressions. Offensiphobia ought to be rejected as it is unsupported by the balance of reason.     

A self-determination theory approach to problematic drinking and intimate partner violence

Problematic drinking has long been established as an important antecedent to the perpetration of intimate partner violence (IPV). As little research has evaluated individual differences beyond anger in this association, this research examines problematic drinking and IPV perpetration through the lens of self-determination theory (SDT), the relational perspective suggesting individuals are motivated to be in their relationship for autonomous (i.e., self-driven) and controlled (i.e., guilt-driven) reasons. We test the hypothesis that problematic drinking is more strongly associated with IPV among those who are controlled in their motivation in four independent samples (N?=?617). College students in relationships completed measures of alcohol consumption, negative alcohol-related consequences, relationship motivation, and IPV perpetration. Results generally suggested that the association between both alcohol consumption and negative alcohol-related consequences and IPV perpetration is only significant among those endorsing greater controlled motivation. This study supports problematic drinking as not being an equal risk factor for all individuals, and suggests that some people may be more vulnerable to problematic drinking resulting in relationship aggression.     

How affordances associated with a distractor object affect compatibility effects: A study with the computational model TRoPICALS

Seeing an object activates both visual and action codes in the brain. Crucial evidence supporting this view is the observation of object to response compatibility effects: perception of an object can facilitate or interfere with the execution of an action (e.g., grasping) even when the viewer has no intention of interacting with the object. TRoPICALS is a computational model that proposes some general principles about the brain mechanisms underlying compatibility effects, in particular the idea that top-down bias from prefrontal cortex, and whether it conflicts or not with the actions afforded by an object, plays a key role in such phenomena. Experiments on compatibility effects using a target and a distractor object show the usual positive compatibility effect of the target, but also an interesting negative compatibility effect of the distractor: responding with a grip compatible with the distractor size produces slower reaction times than the incompatible case. Here, we present an enhanced version of TRoPICALS that reproduces and explains these new results. This explanation is based on the idea that the prefrontal cortex plays a double role in its top-down guidance of action selection producing: (a) a positive bias in favour of the action requested by the experimental task; (b) a negative bias directed to inhibiting the action evoked by the distractor. The model also provides testable predictions on the possible consequences of damage to volitional circuits such as in Parkinsonian patients.     

Fresh Start: A Multilevel Community Mobilization Plan to Promote Youth Development and Prevent Violence

While much has been written about community mobilization for health, few detailed expositions of the formation of community mobilization, especially focused on youth violence prevention exist. The Columbia Center for Youth Violence Prevention, in collaboration with the UNIDOS Inwood Coalition, developed a Community mobilization plan to guide youth violence prevention in Inwood. The plan was developed within the context of an evidence-based organizing framework-Communities that Care (CTC) and takes a multi-level approach to service coordination that includes activities at the Individual, Family, Block, Organizational and Built Environment levels. This article describes how the Community mobilization plan was created, illustrates the use of evidence-based practices to lead to the development of the plan, outlines the plan's community/organizational activities, and summarizes the principles and processes that can be replicated in other communities seeking to start their own community mobilization efforts to reduce youth violence.     

Pigeons' memory for number of events: Effects of intertrial interval and delay interval illumination

In Experiment 1, pigeons were trained at a 0-s baseline delay to discriminate sequences of light flashes (illumination of the feeder) that varied in number but not time (2f/4s and 8f/4s). During training, the intertrial interval was illuminated by the houselight for Group Light, but it was dark for Group Dark. Testing conducted with dark delay intervals produced a strong choose-small bias in both groups. All birds then received baseline training with a 5-s dark delay and were subsequently tested at shorter and longer dark delays. A choose-small bias was again observed at delays longer than the training delay, while a choose-large bias occurred at delays shorter than the training delay. Differentiating the ambient chamber illumination during the intertrial interval and the delay interval did not attenuate choose-small or choose-large effects. In Experiment 2, all birds received baseline training with a 5-s illuminated delay and were subsequently tested at shorter and longer illuminated delays. A choose-large bias was observed at delays longer than the training delay, while a choose-small bias occurred at delays shorter than the training delay. In Experiment 3, on intermittent test trials, when the duration of the second flash on small-sample trials was equal to the total flash duration on large-sample trials (i.e., 1600 ms), accuracy fell to approximately chance. These results suggest that pigeons discriminated the sequences of light flashes that varied in number but not in total duration of the sequence by relying on other temporal properties of the sequence rather than by using an event switch to count flashes.     

The processing of verbs and nouns in neural networks: insights from synthetic brain imaging

The paper presents a computational model of language in which linguistic abilities evolve in organisms that interact with an environment. Each individual's behavior is controlled by a neural network and we study the consequences in the network's internal functional organization of learning to process different classes of words. Agents are selected for reproduction according to their ability to manipulate objects and to understand nouns (objects' names) and verbs (manipulation tasks). The weights of the agents' neural networks are evolved using a genetic algorithm. Synthetic brain imaging techniques are then used to examine the functional organization of the neural networks. Results show that nouns produce more integrated neural activity in the sensory-processing hidden layer, while verbs produce more integrated synaptic activity in the layer where sensory information is integrated with proprioceptive input. Such findings are qualitatively compared with human brain imaging data that indicate that nouns activate more the posterior areas of the brain related to sensory and associative processing, while verbs activate more the anterior motor areas.     

Audiotactile temporal order judgments

We report a series of three experiments in which participants made unspeeded 'Which modality came first?' temporal order judgments (TOJs) to pairs of auditory and tactile stimuli presented at varying stimulus onset asynchronies (SOAs) using the method of constant stimuli. The stimuli were presented from either the same or different locations in order to explore the potential effect of redundant spatial information on audiotactile temporal perception. In Experiment 1, the auditory and tactile stimuli had to be separated by nearly 80 ms for inexperienced participants to be able to judge their temporal order accurately (i.e., for the just noticeable difference (JND) to be achieved), no matter whether the stimuli were presented from the same or different spatial positions. More experienced psychophysical observers (Experiment 2) also failed to show any effect of relative spatial position on audiotactile TOJ performance, despite having much lower JNDs (40 ms) overall. A similar pattern of results was found in Experiment 3 when silent electrocutaneous stimulation was used rather than vibrotactile stimulation. Thus, relative spatial position seems to be a less important factor in determining performance for audiotactile TOJ than for other modality pairings (e.g., audiovisual and visuotactile).
