Stimulus-response compatibility and the motor system

Three experiments examined stimulus-response (S--R) compatibility relationships with the stimulus array perpendicular to the response array. In Experiments I and II, stimuli indicated right and left positions, while the responses were movements up and down. The mapping right/up and left/down was preferable for the right hand, but the reverse mapping was preferable for the left hand. In Experiment III, the stimuli indicated up and down positions, while the responses were movements to the right and left. In this case, the mapping up/left and down/right was preferable for the right hand, and the reverse mapping was preferable for the left hand. The results are most easily explained by assuming that counterclockwise rotational movements are preferable for the right hand, while clockwise is preferable for the left. These preferences are manifest through combinations of implicit movements towards the stimulus and explicit movements towards the response key. This principle is shown to provide a simpler explanation for some previously reported S-R compatibility effects.     

Suicide Ideations,Suicide Attempts,and Completed Suicide in Persons with Pathological Gambling and Their First‐Degree Relatives

We examined the relationship between suicidal ideations and attempts in 95 probands with pathological gambling (PG), 91 controls, and 1075 first‐degree relatives. The results were analyzed using logistic regression with generalized estimating equations. Thirty‐four PG probands (35.8%) and 4 controls (4.4%) had attempted suicide (OR = 12.12, p < .001); in 13 probands, the attempt occurred before PG onset. Lifetime suicidal ideations occurred in 60 PG probands (63.2%) and 12 controls (13.2%) (OR = 11.29, p < .001). Suicidality in PG probands is a marker of PG severity and is associated with greater psychiatric comorbidity. Offspring of PG probands had significantly higher rates of suicide attempts than control offspring.     

Place and Philosophical Topography: Responding to Bubbio,Farin and Satne

ABSTRACT

Diego Bubbio, Ingo Farin and Glenda Satne have advanced a range of comments, questions and challenges relating to the ideas and arguments set out in the new edition of my Place and Experience (2018). Rather than address each of my interlocutors separately, my responses here are organized around four main topics: the relation between space and place, including the nature of space; the relation between place and subjectivity, and the foundational role of place; the relation between place and conceptuality; and the relation between place and normativity.     

Correlates of Suicidal Ideation in Physically Injured Trauma Survivors

Epidemiologic studies have documented that injury survivors are at increased risk for suicide. We evaluated 206 trauma survivors to examine demographic, clinical, and injury characteristics associated with suicidal ideation during hospitalization and across 1 year. Results indicate that mental health functioning, depression symptoms, and history of mental health services were associated with suicidal ideation in the hospital; being a parent was a protective factor. Pre‐injury posttraumatic stress disorder symptoms, assaultive injury mechanism, injury‐related legal proceedings, and physical pain were significantly associated with suicidal ideation across 1 year. Readily identifiable risk factors early after traumatic injury may inform hospital‐based screening and intervention procedures.
