assist you in understanding two common sleep theories‚ recuperation and circadian‚ which provide different answers to these questions. Depending on which one you support‚ it may change your outlook on sleep and your current sleeping habits. Categorize each characteristic under the correct theory—recuperation or circadian—by placing an “X” in the appropriate column. Then‚ answer the questions that follow. Recuperation Circadian Sleep restores the body to a state of homeostasis. X Sleep plays

The Circadian clock generates physiological and behavioral rhythms with a period roughly 24 hours. It is thought that Circadian dysfunctions underlie the pathogenesis of many psychiatric disorders such as mania-like behavior and bipolar disorder (McClung‚ 2013). Attention Deficit Hyperactivity Disorder (ADHD) is one of the most widespread psychiatric disorders in humans. Somewhere between 3 and 5% of the population is affected by ADHD (Geissler and Lesch‚ 2011). The ADHD phenotype is characterized

Discuss the consequences of disrupting biological rhythms Biological rhythms are controlled by endogenous pacemakers‚ which are our internal biological clocks and these rhythms are also affected by exogenous zeitgebers‚ for example light‚ food and noise. The most common disruptions of our biological rhythms occur due to aeroplane travel‚ which results in jet lag‚ and also due to shift work‚ resulting in shift lag. (AO1) Shift work described a type of job in which individuals have to be alert

evaluate research into one or more biological rhythms” [research = theories and studies] There are three main biological rhythms‚ which are called infradian‚ circadian and ultradian. Ultradian rhythms occur multiple times in one day. Circadian rhythms are cycles‚ which occur once a day‚ so within the 24 hours such as the sleep-wake cycle. Infradian rhythms are less frequent once in a day such as the menstrual cycle or hibernation. The research into these rhythms offers an insight into how the body is

Discuss the disruption of biological rhythms 24m One example of disruption of biological rhythms is due to shift work and shift lag. This disrupts your sleeping pattern because it means you are required to be alert at night‚ so need to sleep during the day. This reverses and disrupts your circadian rhythm‚ becoming desynchronised where it is no longer entrained by EZ’s. There are many consequences of desynchronisation such as sleep deprivation. Shift workers find it hard to sleep during the day

the consequences of disrupting biological rhythms (24) A rhythm is something that is regularly repeated. All living organisms experience rhythmic changes which tend to coincide with seasonal or daily environmental changes. Most organisms have an internal biological clock called endogenous pacemakers‚ which are influences by external environmental factors called exogenous zeitgebers‚ these control periodic changes. The sleep wake cycle is a circadian rhythm that repeats itself every 24 hours. However

biological rhythms A rhythm is something that is regularly repeated e.g. eating several times a day. These rhythms are repeated over different intervals and they are governed by both internal (endogenous) and external (exogenous) factors. An endogenous pacemaker is something internal that sets the rhythm‚ and an exogenous zeitgeber is something external that affects / sets the rhythm e.g. light. A biological rhythm that depends upon endogenous pacemakers is the sleep/wake cycle circadian rhythm

CIRCADIAN CYCLE AND ADOLESCENTS’ NONVERBAL INTELLIGENCE By Dr Mrs. Santa Misra‚ Department of Psychology SSS College for Women‚ Bhubaneswar‚India Abstract ‘Circadian Cycle’‚ the biological clock within the organism‚ is the cyclic changes in bodily process occurring within a single day basing on our conscious awareness which is generated endogenously by the anterior hypothalamic suprachiasmatic nuclei and modulated by exogenous factors. In other words‚ the state of activity and arousal level

The article The Rhythm of Change mentions that "change has to be managed with a profound appreciation of stability." Is this statement contradictory? My first thought was if something changes it is not stable. But even though this might be true‚ the rhythm of change is stable. The article states that there are three categories of change that make up "The Change Triangle"‚ dramatic‚ systematic‚ and organic change. Dramatic change is something that happens in emergency situations or in a crisis

Circadian Interference Establishment of a ‘normal’ circadian rhythm in sleep/wake cycle and core body temperature and the effects of a sleep deprivation event on that rhythm. Introduction: Circadian rhythms are well documented and researched all over the natural world. Humans are subject to a circadian rhythm as well; being naturally diurnal animals‚ humans sleep during the night and are active during the day. It is also known that circadian rhythms affect more than just sleep wake cycles‚ but
