This study evaluated the separate and combined effects of behavior modification 2 doses methylphenidate (MPH; 0.3 0.6 mg/kg) compared with baseline (no a placebo) on classroom academic performance 31 ADHD (attention deficit-hyperactivity disorder) boys attending summer treatment program. Results revealed significant both interventions, mean effect size medication being more than twice as great that modification. Relatively small incremental value was gained by higher dose or addition...
ABSTRACT Aims Players can wager on multiple lines of modern slot machines. When they spin and fail to gain any credits, the machine goes into a state relative quiet. By contrast, when win, these spins are accompanied by reinforcing sights sounds. Such reinforcement also occurs amount won is less than wager. We sought show that ‘losses disguised as wins’, or LDWs, would be arousing wins, more regular losses. Measurement participants measured skin conductance response (SCR) amplitudes...
Abstract Aims In multi‐line slot machines, players can wager on more than one line per spin. We sought to show that preferred over single‐line games, and certain game features could cause play feel rewarding. Measurement Participants Reward was measured using post‐reinforcement pauses ( PRPs ) following each outcome (the time between delivery the next spin). Gamblers n = 102) played 250 spins a 20‐line one‐line (answering questions about experiences session). Playing one‐line, small credit...
Slot machine wins and losses have distinctive, measurable, physiological effects on players. The contributing factors to these remain under-explored. We believe that sound is one of key factors. Sound plays an important role in reinforcement, thus arousal level stress response It the use for positive reinforcement particular we influences player. In current study, investigate psychophysical responses slot play. A total 96 gamblers played a simulator with without being paired reinforcement....
When C, a digit-color synaesthete, views black digits, she reports that each digit elicits highly specific color (a photism), which is experienced as though the was externally projected onto digit. We evaluated this claim by assessing whether C's photisms influenced her ability to perceive visually presented digits. C identified and localized target digits against backgrounds were either congruent or incongruent with of photism for The results showed poorer at identifying localizing on than...
We describe the extraordinary memory of C, a 21-year-old student who experiences synesthetic colors (i.e., photisms) when she sees, hears, or thinks digits. Using three matrices 50 digits, we tested C and 7 nonsynesthetes to evaluate whether C's photisms influence her for One matrix consisted black whereas other two digits that were either incongruent congruent with photisms. recall incongruently colored was considerably poorer than congruently The did not show such differences in their...
Contrast enhanced magnetic resonance imaging (CE MRI) is the most sensitive tool for screening women who are at high familial risk of breast cancer. Our aim in this study was to assess cost-effectiveness X-ray mammography (XRM), CE MRI or both strategies combined. In total, 649 were enrolled MARIBS and screened with resulting 1881 screens 1–7 individual annual events. Women aged 35–49 years cancer, either because they have a strong family history cancer tested carriers BRCA1, BRCA2 TP53...
Multiline slot machines allow for a unique outcome type referred to as loss disguised win (LDW). An LDW occurs when player gains credits on spin, but fewer than their original wager (e.g. 15-cent gain 20-cent wager). These outcomes alter the gambler's play experience by providing frequent, albeit smaller, credit throughout playing session that are in fact net losses. Despite this negative overall value, research has shown players physiologically respond LDWs if they wins, not also create...
Abstract Loot boxes are a purchasable video-game feature consisting of randomly determined, in-game virtual items. Due to their chance-based nature, there is much debate as whether they constitute form gambling. We sought address this issue by examining players treat loot box rewards in way that parallels established reward reactivity for monetary slots play. Across two sets experiments, we show containing rarer items more valuable, arousing, rewarding and urge-inducing players, similar the...
In modern casinos, multiline slot machines are becoming increasingly popular compared to traditional, three-reel machines. A paucity of research has examined how the unique presentation near-misses and use a stop button in impact erroneous cognitions related perception skill agency during play. Our goal therefore was determine prevalence pertaining near-miss outcomes usage then see whether affected players' experiences winning, losing outcomes. We recruited 132 gamblers from casino Ontario....
We have previously reported that loss-of-function mutations in the cathepsin C gene (CTSC) result Papillon-Lefèvre syndrome, an autosomal recessive condition characterized by palmoplantar keratosis and early-onset, severe periodontitis. Others also CTSC patients with prepubertal periodontitis, but without any skin manifestations. The possible role of variants more common types non-mendelian, periodontitis ("aggressive periodontitis") has not been investigated. In this study, we investigated...
Through the Freedom of Information and Protection Privacy Act, we obtained design documents, called PAR Sheets, for slot machine games that are in use Ontario, Canada. From our analysis these Sheets observations from playing watching others play games, report on structural characteristics Ontario slots their implications problem gambling. We discuss such as speed play, stop buttons, bonus modes, hand-pays, nudges, near misses, how some wins fact losses, two identical looking machines can...
Near-misses in slot machines resemble jackpot wins but fall just short (e.g. two red sevens on the payline and a third above). These outcomes have been shown to be subjectively arousing that promote further machine play. We assessed psychophysical responses of 65 participants wins, losses near-misses while playing simulator. Skin conductance were significantly larger for than either or losses. Similarly, heart rate deceleration was arousal not mediated by players' problem gambling status –...
High familial expressed emotion (EE) reliably predicts 9-month relapse rates in schizophrenia patients. Difficulties interpreting the EE-relapse finding arise, however, because EE is usually assessed during a hospital admission, yet following discharge predicted. Researchers Scotland relatives while patients were out of hospital; using conservative criteria, they failed to find higher subsequent 6- and 12-month among living high-EE homes (McCreadie Phillips 1988). Our goal was determine...
